is the opposite of doing a divebomb (going down towards body)with a whammy bar on a Guitar. mostly heard from Dimebag Darrells music where he would pull off a harmonic dip the bar and bring it up (requires a floydrose style bridge for really high squeals)
When you are about to cum: pull out, position your partner so he/she is laying down (face up), stand over him/her, and try to cum in his/her mouth from above. Sometimes a competitive grading system is involved: 10 points for divebombing the mouth and -5 for divebombing the eye (because, when semen ejaculates at 30 miles per hour, a divebomb can be quite dangerous).
Oh man, I divebombed this chicklast night soo hard. Thankfully I didn't hit her eye. I need to make it to divebomb finals.
When the girl does a hand stand with her ass in the air, the the man subsequently runs at her fully erect and dives attempting to land directly in her.
