A chaunchburger is positionally specific. When a vag requires oral attention, but the chick refuses to roll off of her side, you’re left with a chaunchburger. Not unlike a Wendy’s hamburger. Note, finding condiments, especially bacon, is not a good thing.
I went over to Paul’s to tap his mom last night, but his dad was laying next to her in. She rolled onto her side and gave me her chaunchburger.
