When receiving a blow job just prior to climaxing make some smart ass comment to get the girl sucking your cock to laugh just as you blow your load. The result will be the same as making a friend laugh while they are drinking a glass of milk - only creamier.
1. I met this really hot girl at the club last night and ended up ghosting her.
2. My girl was blowing my the other day and I told her that stupid joke of yours. It totally ghosted her.
