Jack In The Box 

Before climaxing during a blowjob slamming your partners head down, thus making her deep-throat your penis and ejaculating down her throat.

When talking to my girlfriend she informed me the she spits and doesn't swallow. so mid-blow job I slammed her head down and gave her a jack in the box.

Jack-In-The-Box 

While one is having sexual intercourse with his girl and they are fucking but while his penis is in her he grabs the end of it and "shakes hands with mr. happy" until he climaxes.

Friend: "Hey man what did you do last night, you look exhausted"
You: "Oh well man, Jack-In-The-Box came pretty "handy" last night near the "end" of my session with my wife."
