After receiving oral sex from his partner, he then French kisses his partner while they spit his ejaculate into his mouth.
A man's ejaculate is usually a white color. After a few moments, if not disposed of, it will congeal into a semi hardened texture. It can then be rolled into a spherical shape like a ball. Thus the term snowballing. Also know as snowblowing.
when a girl suck ur dick and you blow a wod in her mouth. then she spits the wod in ur mouth and you do it back to her a couple of times. finally, you two make out while swapping the cum back and forth. VERY FUCKIN GROSS AND NEVER DO UNLESS YOU HAV A SIC MIND
The super gay one is, when a man barebacks another man, then cums, the reciever ejects it out of his bowls, and another man sucks it up and makes out with whoever, and they continue the chain of making out, snowballing it to get larger and larger.
I cumed alot in this guy, and they pushed it into the guy next to him, which in return got bigger and bigger. (Snowballing)
