"How do you accidentally kiss someone? Did she slip on a rug, and your lips broke her fall?"
—Topanga Lawrence, Boy Meets World
- In a fit of celebration, someone high on excitement unleashes their passion by grabbing and kissing the nearest set of lips before they realize what they're doing. Unplanned Smooch of Victory.
- After a Crash Into Hello or something resembling, the colliders' lips always have a strange tendency to connect. Rarely, if ever, are the painful implications of teeth colliding against teeth at high speeds addressed.
- Then there are the foreigners (including aliens) who kiss someone without realizing what it means in the other participant's culture/planet.
This trope actually occurs in Real Life, only not to the same extent as it is shown in fiction. Can turn into a Gay Moment.

Miyako, having won the club's gambling event, is to be awarded a kiss by Tamaki, but in a surprise Twist Ending, Kyouya announces that the honor would go to Haruhi instead. She goes to kiss Miyako on the cheek, but Tamaki rushes in, slips on a Banana Peel, and pushes Haruhi onto the other girl's lips. The club's female clientele goes crazy, and Kyouya sits back to himself thinking, "Nice..."
- The same scenario plays out at the end of episode two of the anime, after Haruhi helps one of Kanako's male suitors to admit that he loves her. He lets her go ahead with it, thinking it'll be a simple peck on the cheek, symbolizing the end of her hopping from favorite host to favorite host. Nope.
- At the end of chapter 72, we finally get one of these between Haruhi and Tamaki.
- The chapter after that lampshades the unlikelihood of accidental kisses occurring like crazy, with pointed references to shoujo manga.

He closes his eyes and psychs himself up to kiss Unlucky Childhood Friend Manami, but his horndog male friend, the Chivalrous Pervert Kazuki, chooses that moment to enter the scene in precisely that place. Mugi is mortified about Kazuki stealing his first kiss, and Kazuki tells Mugi it "serves him right" for playing a kissing game without letting Kazuki in on the fun.

- In MAR, Ginta and Snow get their first kiss mixed with Crash Into Hello when Ginta throws a fire ARM to melt the ice she's encased herself in. Her fall is broken by his lips, and they both run to others in the group to confirm that they did actually kiss. Ginta later gets told off by her guardian for 'stealing' the Princess' lips.
- Later , even after she successfully averts kissing his lips a second time (anime dream episode only), when she gets freed from the trap she's in, the above sequence is followed again, although this time it's less of an issue, since it's no longer their first time, and they're reasonably past the stage of 'I don't even know/like him/her'.
- Although the First Kiss implication is left questionable, Asu no Yoichi has a similar setup as the MAR scene above, with Yoichi falling three stories and being 'caught' by Ibuki's lips. The fact that the gift he was jumping after coming between their lips seems to be ignored in the wake of the actual kiss.
- Hanaukyo Maid Tai La Verite episode 12. After Ryuuka makes another proposal of marriage to Taro, she trips and falls on top of him, kissing him in the process.

- Akira Yuki from Virtua Fighter the anime series accidentally lands a kiss on Pai-Chan in the first episode when the Koenkan are interupting a chinese dumpling Eating Contest as he's flying across a restuarant trying to eat one of the dumplings (long story). Pai has never had a First Kiss and she's a type A Tsundere, so the result is predictable.
- Occurs between Mayu and Reika in the last episode of Goshuushou-sama Ninomiya-kun.
- To LOVE-Ru: Rito and Ren collided mouth-first while both were trying to kiss Lala. Oblivious to the implications (and the way the boys were gagging), Lala expressed pleasure that they'd become such good friends so quickly. This "kiss" also later resulted in Run's "sister" Run having a major crush on Rito.
- It's not entirely clear, but this may have occured in Sonic X when Tails "heroically" (cough) pushes Cosmo out of the way of a falling disco ball. He ended up on top of her. A kiss was quite apparently a possibility, blocked from that angle.
- Bart Allen (Impulse) had one of these with his friend Carol. After consistently screwing up while trying to learn baseball, he succeeds in winning the game and Carol smooched him without planning to in front of everyone.

One man goes to kiss Miss X and the camel sticks her head out of a window from outside to lock lips with him for a long smooch. Hearts appear in the air when their lips seperate. Another runs to embrace Miss X and finds he is making out with the camel. It seems that she is a good kisser because both men enjoy pressing their lips against her and smile after having done so. That is until they open their eyes and realize they made out with an animal!
