someone who ruins it for everyone. in effect it is some one who, like an iceberg, sinks the whole ship. they usually dont mean to do this but their lack of foresight or the ability to think before they speak usually ends in the misfortune of everyone else around them. This may be someone who's very presence or personality is so objectionable that they ruin your day or night. you do not want to be an iceberg!

Like a grenade, an iceberg is a girl that you don't want around. This is a girl with a boyfriend; not bad on top, but beneath the surface there's a BIG problem.
Why are grenades and icebergs even allowed in the house?

A premeditated sexual act that involves freezing a shit in tupperware and concealing until intercouse. Right as the woman has an orgasm, you take out the frozen turd and flop it on her chest shouting "THERE'S THE ICEBERG BITCH!"
I opened Jim's refrigerator only to find it stocked not with edibles, but layer upon layer of ready to go icebergs.

"hey man, you gonna flush that shit? I need a couple icebergs for my girlfriend this week"

"you never see the iceberg until it is too late..."

When you shit a long turd out that goes down the toilet bowl, but is still long enough to protrude out of the water.
