look up any word, like pussy:
When a man has an orgasm without ejaculating. A portmanteau of dry and orgasm.
I thought I had creamed my shorts right in the middle of my speech, but fortunately it was only a drygasm.

A dry orgasm.
Generally occurs after an excessive amount of wet (conventional, ejaculatory) orgasms in too short a period of time. The testes lack the requisite time to "recharge" and thus no ejaculation accompanies the climax.
Also possible: a discharge void of sperm, comprising only the fluids, released by the prostate, through which sperm are carried. This discharge would be clear in color, much smaller in volume as compared to a regular ejaculation, and much less viscous.
I had sex five times and jerked off two times in one day, and when I jerked off the third time, I had a drygasm.

The trained ninja art of having unprotected sex and leaving no trace other than slight prejac. A black belt won't even juice a little. Many collar popping cocks have been known to be notorious at this trick as if trained in the dark arts. In the developed world this is known as "heart breaker syndrome" commonly seen to be politically ruled by feminists. This is perceived as philosophy gone to the birds aka science without actual empirical data. See: subliminal mind fuck.
The hockey team threw a house party with a keg of la blatt's blue in a brown bottle of rooooooofies and invited all the cheerleaders from a radius of 300 miles to unwittingly practice drygasms on their incoherent subjects.

The act of masturbating and feeling the climax even though an orgasm wasn't truly achieved due to there being no semen being released
I had a really nice wank, but it was ruined because I had a drygasm (no mess though)
