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”
“There’s vomit on his sweater already, Mom’s Spaghetti, he’s nervous”
