A fun kids game in which you take turns throwing at least ten gerbils into a bucket of water and then taking turns bobbing (with your mouth) for the gerbils. The fastest time, in collecting all the gerbils, wins. If any of the gerbils die during a contestants turn, they must receive a kick to the mouth by the player who's turn is after. This game is illegal in 3 countries. It was most recently banned in the UN in March of 2009.
Hey little Johnny, how about a good 'ol gerbing game for your birthday party tomorrow?
The act of sticking your hand up a girl while she's on her period and pulling out the biggest chunk of clot you can find (occasionally rolling up multiple clots into a sphere) and either throwing or eating them, most commonly the latter.
"Dude, my girlfriend let me glorb her last night! It was awesome"
"I need to find someone that's okay with glorbing during sex"
