A gusher made when a man with a bitch ass latex allergy or a hippie releases his slimy cum seed into a lambskin condom and his girlfriend, or more likely in this case boyfriend, bites on the condom and it explodes in their mouth like a gusher
you hear that bitch ass, troy, ate a giant nasty lambskin cumbuster gusher from his twinky hipster boyfriend?
Premature ejaculation. One pump chump. Wet dreams.
We didn't even get to have sex due to spontaneous cumbustion.
An orgasm so intense you spontaneously combust
He/she died of cumbustion!
It is when you masturbate and you let cum out of your penis in less than 2.5 seconds.
I cumbusted yesterday and it makes me sad it went fast.
