When you're hooking up and she's on her period and it gets all over your balls.
Jim: Did you fuck her?
Tom: Bro It was mom's spaghetti all up in there.
There's vomit on his sweater already, mom's spaghetti
When it’s your moment to shine. This is you’re one shot. 15 minutes of fame.
Yo tobias you got this!
I know it’s my mom’s spaghetti!
A funny way of saying that you or someone else is nervous. It’s a lyric form an Eminem song called “lose yourself” from the 8 mile sound track
The example in the song/movie:
“There’s vomit on his sweater already, Mom’s Spaghetti, he’s nervous”
