To screw up really badly. To miss the point of something and do something else. Comes from the idea that when having sex, one misses the pussy and starts humping a woman's gooch, the area between her pussy and ass, making a fool out of himself and screwing up. Don Eimus is a person screwed the gooch when he disrespected some thugish black-woman basketball players.
"I knew I should't have nailed Monica Lewinski... Damn i screwed the gooch."
I did my report completely wrong. Man i really screwed the gooch."
"Matt, youre' a jew so don't have sex with that terrorist's daughter. You'd have to be a total dumbass to screw the gooch like that"
Molly Ashby always loved the opportunity to tell her fellow board members that management screwed the pooch last quarter; Brian Watson creamed his pants when she said that.
When no boy likes a girl cause she looks like a man+ape fused together so she uses a scewdriver as a sex toy and then later using the same screwdriver as a spoon to mix her tears sweat and apple juice (while putting it on her snapchat story *essential*) then putting it in a container as a potion. She will then put it in a boys drink/food to make them fall in love with her. Work best with white/mix race boys.
'Im soo sad, no boy loves me cause i look like harambe'
Code word for sex, when walking up to a stranger (prearranged) at the back of a Co-Op. Must get out IPhone, pretend to not understand directions and say screwfix in strangers ear. The recipient has to suck his own finger in his mouth and then rub it in other chaps ear.
