A sexual game when after someone has had sperm ejaculated into their mouth they hold it orally rather than spitting or swallowing, then french-kiss with their partner.

snowballing

A sex game.

Passing cum from person to person in such a way that the amount of cum increases.

Man cums in womans mouth, she spits cum into another womans mouth and a man cums in it too. She spits this into another womans mouth and so it goes on, back and forth till the last woman has to swallow a massive glop of cum. The "snowball" effect, see?

A very kinky sexual game when after someone has had sperm ejaculated into their mouth they hold it orally rather than spitting or swallowing, then french-kiss with their partner. It can also apply with two guys or a group with at least one guy involved (no duh).

Aftering Russell ejaculated in Kat's mouth they started snowballing.

Snowballing mates 

The art of cum swapping between good male friends. Where After fellatio has been performed, the one with a gob full stands over the other on and transfers semen and saliva into mouth.

Connor had a long glistening shaft in his mouth, whilst jack screamed, "hold onto your hat love, im about to blow your brains out". Connor, with a gob full stands over pale skinned jack and uses his big lips to llama spit the cum into jacks mouth. Jack swallows and looks to his family who give him thumbs up, to which rick says, "Now thats what i call snowballing mates".
