Lickspittle

"Find a lackey. I cannot stress the importance of this enough. It's a crucial step on the ladder to becoming popular. How are people going to know you're awesome if there's not some other party reminding them of it on a regular basis? ... Don't pick someone prettier than yourself or with high self-esteem. The thrill of living vicariously through you, the superior person, should be their greatest joy in life."

- Memoirs of an Internet Legend

Pretty much the lowest of the low, the Lickspittle is someone who willingly makes themselves the whipping boy of someone with power and/or fame. More than a Yes-Man, more even than a Professional Butt-Kisser, the Lickspittle sets no limits to the depths to which he will abase himself in order to curry favor with the object of his adoration. If they have an opinion, he'll copy it. If they're in an argument, he'll take their side. If they ever suffer a moment of self-doubt, he'll be there to cheer them up with some assurances of how great they are. He'll eagerly sacrifice friends, family and dignity to prove his complete and utter worship.

Compare Professional Butt-Kisser and Yes-Man. The primary difference between a Lickspittle and either of these is that a Lickspittle is disgustingly obvious about it, to the point of having no pride or self-respect, while at the same time unswervingly loyal to his "master".

"Lickspittle" isn't one of those Esoteric Trope Names we're famous for, by the way -- it's a standard English word dating back to 1825, meaning an obsequious brown-nosing toady -- in case we haven't already made that clear enough.
