Sorry that was a typo meant to say 'you snowballed your own cum' I wasn't implying anything but have only imagined two women in a threesome snowballing my cum before swallowing it. 
You've been watching too much porn, Chinadoll!! Given that most punts arranged on AW are going to be 1-2-1, the implication of snowballing appearing on a girl's "likes" list is that she's expecting to take your cum into her mouth and, ideally, after sloshing it about a bit (which adds to the volume, hence the term "snowballing") dribble it into your mouth. You then have the option of swallowing it or you can trade it to and fro with her a few more times until one of you gets bored.
The first time I tried it I was feeling exceptionally horny, which is when I tend to try things for the first time that I normally wouldn't contemplate doing. To my surprise, I rather enjoyed it. The girl seemed surprised when I swallowed and said she was impressed - which of course stroked my ego. One thing which decided me to try it, is that I've always believed that you shouldn't ask someone else to do something that you're not prepared to do yourself. There are obvious limits as to how far you can apply this principle. I can get someone pregnant, but I can't have a baby myself. But in general, I like this idea. I enjoy anal but used to feel a bit guilty about it until I tried it myself. Now anal is guilt-free for me, as long as the woman has freely consented and says she enjoys it, too.
