The result of a sexual rendezvous on a rooftop; usually affecting the naked bum of the person spending the most time on the bottom. Symptoms include redness, sore cheeks and limited movement. Treatment includes massage and consumption of alcohol. You may want to go back up on the roof and take 2, but remain on top; therefore evening up the score. Now you both are shingle-assed.
we roof-hung last night and I rode him like a mechanical bull... he got shingle ass for sure!
