Delaware Marshmallow

A sex act wherein immediately after ejaculating into someone's mouth, you forcefully open hand slap both sides of their face (like Belushi's "zit" in Animal House), causing the person to forcefully eject the semen... along with saliva and, if done correctly, a little blood... onto the rug.

Julie told me she'd be willing to try anything once, but apparently a Delaware Marshmallow is just a step too far.
