To suck semen out of ones ass after anal intercourse and snowball (spit) it back in that persons mouth.
After Darren came in Kelli's ass he felched the semen back out and felchballed her.

After vaginal intercourse you allow the semen to drip down to her asshole, eat it out, and then spit it back into her mouth. It's a mixture of felching and snowballing.
"Want to try a felchball tonight? After that donkey punch I'm sure it's nothing for you..."
