Cumboating 

The act of ejaculating onto a non porous surface (such as PVC mattress cover) and then sliding around on it.

Chris blew his load all over the bed, then cumboated around whilst his girlfriend looked on horrified. She did not approve of his cumboating fetish.

cumburping gutterslut 

Essentially, a promiscuous female of massive, shocking, unheard of proportions. Her breath consistently stinks of dick snot, a substance whose stench does not age well. That is one of many reasons why these beasts existence is so perplexing. Who allows them to defile their sacred anatomy? I personally enjoy referring to inferior prudish women as cumburping guttersluts since it undoubtedly causes them great confusion, a gaping mouth and an urge to slap you. These factors usually provide for phenomenal comedy.

Jose Contreras: How does the prostitute look across the street?
Bruce Lee: What the cumburping gutterslut? She looks like she started meth at age 7 and lost her teeth to a gang of horny Hell's Angels.

cuntbusting 

Attacking a girl's genitals, whether for fun or for reasons of self defense. While not as easy of a target as a man's testicles, the clitoris is every bit as sensitive. Even a playful slap, while not particularly harmful, can still be enough to make a girl double up and fall to the ground in pain. On the other hand, a full force kick can crush the clitoris up into the pelvic bone, compressing it. Since the clitoris is so tender, this will cause the girl incredible amounts of pain, and in some cases, severe injury, such as vulvodynia, bruising of the vulva and clitoris. In extreme cases, the girl may experience bruising to her pelvic bone as well. Severe cases of cuntbusting also carry the potential of emotional trauma, since the average girl tends to be more sensitive than the average boy.

For some reason, a surprisingly large number of (mostly younger) girls are unaware of their genitals' tenderness. Yet when kicked full force in the groin by the same person, girls are going to suffer just as much (if not even more) pain as boys, because of the double shot on the clitoris and the pelvis. The clitoris is located slightly higher, so when kicking a girl in the groin, the attacker aims higher and hits the clitoris and the pelvis, which is located right behind it. On the other hand, the testicles hang lower, so when kicking a boy, only his testicles are hit, and not his pelvis. It's still incredibly painful for a boy, but he won't have pelvic bruising to add to his injuries.

Danny: So Sarah tried to kick me in the nuts over the last bagel this morning.

Alec: That's a bad idea, considering you're a black belt in karate... what'd you do? You let her have it?

Danny: Let's just say I gave my little sister a cuntbusting she'll never forget!

Alec: How so?

Danny: I kicked her so hard in her little pussy that she dropped to the ground immediately and burst into tears.

Alec: That'll teach her.

Danny: She's probably still crying.

Spontaneous Cumbustion 

The process by which, through the ingestion of an unruly quantity of phosphorous, one's ejaculate spontaneously erupts into flames upon expulsion from the penis causing widespread fear and panic.

Dave and Marie were dating until Dave's spontaneous cumbustion all over Marie resulting in a sudden case of the funerals.
