the new slang word used by 8th graders who think they're cool meaning hottie. Used when speaking of a male, when speaking of a female; fruit snack is used.
Four steps of gusher:
ugly- G
okay- Gu
good looking- Gus
good looking and nice body- Gush
good looking and hot body- gusher
REALLY HOTT AND REALLY NICE BODY- MAJOR GUSHER!
The most amazing fruit snack ever created. It is both incredibly tasty and fun to eat because there is goo inside that gushes out when you eat them. Presently, the gush inside is blue which then turns your mouth blue, and who doesn't love it when their tongue changes colors? It most commonly comes in three delicious flavors: strawberry, watermelon, and tropical (which is the best).
