eat my hitch
When you're in a big ass truck and someone wants to ride your ass or you want someone to deep throat your junk (male) or swallow your butt (female)
He pulled up beside me and said, 'Eat my hitch or I'll leave you in the ditch!'
She said, 'I'm gonna ride your ass and eat your hitch!'
He sent me a DM: 'You better eat my hitch or I'll beat your ass!'
