eat my hitch
When you're cruising in a huge dually and someone wants to ride your ass or you want someone to suck your cock (male) or eat your butt (female)
My cousin saw me in my truck and yelled, 'Eat my hitch!'
He said, 'You better eat my hitch or I'll run you over!'
She texted me, 'I'm coming to your house. You better eat my hitch!'
