Crusty Envelope Sealer 

The act of ejaculating inside ones boxers while worn then forgetting and having your load dry to your thigh. Usually the result of a parental invasion without knocking or late night jerk session.

"Brad, why did you run off last night after we finished dry humping?"

"Oh I just had a Crusty Envelope Sealer I had to open."
