the act of placing one's balls into a woman's mouth; which causes her to look like a chipmunk storing nuts for the winter.
Since Dianne had a large mouth, she was able to perform the Alvin with ease on Mark.

Alvin is someone who seems to be very shy and antisocial at first meet. They usually look asian but are mostly Hispanic. But once you get to know him he is a really caring, funny, smart person that is fun to hang around with. When he has a girlfriend he tries to show his love to her in many different ways but more by giving her hugs. If you ever meet an Alvin try to keep him on his bright side because when he’s not don’t mess with him, he’ll be like a whole other person. Alvin’s are typically adorable and cute but not on the hot side.
Boy A- Alvin is a really shy kid
Boy B- no he isn’t, once you get to know him you’ll know what I mean.
Girl A- He’s adorable but quiet
Girl B- He’s my boyfriend but he’s actually really outgoing once you get to meet him
