Lansing Letter Bomb 

Creative encore to the Des Moines Dip. During a blowjob, pull out the girl's lower lip (like a mailbox) and blow your load between the cheek and gumline. Then, before she can spit or swallow, smack her in the face hard enough to simulate an explosion.

"Hey Lindsay, what the hell happened to your face?"
"Oh, my boss gave me a Lansing Letter Bomb for Secretary's Day."
