You've Been Hazed
Coined by the YouTuber DailyGrace, when a new "viewser" comments on one of her videos, she "hazes the crap" (i.e. makes fun of their username) out of them and "welcomes them into the DailyGrace family" (most of the time she's only guessing, although she has had some repeated commenters in the past). Her hazing usually informs some form of the word "suck".
This definition can be expanded towards making fun of anyone.
