Just to make sure that it isn't understated how much this trope applies, the crowd was WILD the instant his music hit. Like, louder pop than Cena wild.
Rey Mysterio was booed for giving Diesel a 619. And the crowd kept with the Diesel chants after he was eliminated.
Growing the Beard - His run as WWE champion is remembered for being... pretty poor. It's been noted he was the lowest paid WWE Champion because he was the lowest drawing. The highlight of which has to be Brett Hart taking it from him at the Survivor Series (well, that and his PWI Match of the Year with Shawn Michaels.) However, after that, he started becoming a more interesting Heel. He then jumped shipped to WCW and with the NWO became the Magnificent Bastard we know and love.
He's Back: After dropping off the radar since his 2011 Rumble appearance, he returned to cheap shot CM Punk at Summerslam after retaining the WWE Championship, allowing Alberto Del Rio to cash in his Money in the Bank Briefcase and win the title.

He also has a summer house on Fire Island, thank you for asking.
"Kevin Nash was raped on the summer of 92", a meme originating of a fake #MeToo Facebook post supposedly written by Nash. Given 4chan's penchant for Black Comedy, Nash can't be mentioned without a mention of it.
Never Live It Down: "So this is 'where the big boys play,' huh? Look at the adjective--play!" No, Mr. Nash, "play" is not an adjective. Not to mention that sentence came out unintentionally homoerotic.
