To hate as a group on one person. When 3 or more people, gang up on one person and make fun of them. Usually a group of friends who all dont like the same person and make fun of that person when they are together.

Person 2. "Me either, hes such a fag"
Person 3. "Yeh he thinks hes the shit, but hes not"!
Person 4. "haha we're grouphatin on that punk"!
