epcomics who's a giant baby! referring to a forum member who posts rather frequently, starts pointless threads, and/or submits successive posts in an attempt to increase their post count. See here:
Old Skool Post Whores.HUGGLES - A special combination Hug and Snuggle, commonly associated with fan girls.
GLOMP - The ambush variation of the Huggle, also commonly associated with fan girls.
CHEF/PULL A CHEF - An homage to the Isaac Hayes character from SOUTH PARK, and his common response to tense, possibly anger-inciting topics of conversation, "I'm not touching this with a twelve-foot pole!" Basically the same as Pleading the 5th. e.g.: POST #1 "Let's talk about abortion." POST #2 "Whoa! I am pulling a Chef on this one!

"
MEH - A Simpson's-derived slang term that means, "I can't work up anything enthusiasm about this." e.g.: POST #1 "Is anyone going to see HE'S JUST NOT THAT INTO YOU?" POST #2 "Meh.

"
FEH - A slang term derived from The Critic that means, "I'm not going to dignify that with a comment." Basically a slightly more aggressive
Meh. e.g.: "Last night's episode of Family Guy was so funny!" POST #2 "Feh.

"
BLARG/BLARGEN - Swear word replacement of unspecified definition. e.g.: POST #1 "I can't wait to watch HEROES tonight!" POST #2 "It's preempted." POST #3 "Blargen!

"
