Someone who is too drunk or stoned to have a good time at a party or who tries but can't figure out how to act normal.
I am such a goonygoople, I just never know what to say to people at parties and usually end up pooping in the punchbowl or hiding in the bathroom shower stall.
gú-see gú-nee: The act of squeezing a woman in between her legs at the labia, from either the front or from behind. Derives from the word "goosing", to describe pinching a someone's behind, combined with "goony", to denote the specific location as being the "goona" or vagina.
Depending on personal preference, it is either an expression of joy, happiness or delight or an expression of sarcasm in response to a small gain/reward etc.
Joy.
"You got an A+ on your maths test!"
"Goody gumdrops!"
