look up any word, like half chub:
1) When you use a chick-fil-a sandwich to masturbate.

2) When someone performs filatio while eating a chick-fil-a or having just eaten it so that their breath is fresh with chicken and peanut oil.
1) Man it's bad news when I get hungry and horny because I'm liable to forget which hand's doing what and I'll end up giving myself the old chick-fil-atio.

2) Big girls give the best head, but sometimes you need to entice them with a free sandwich...Chick-fil-atio!

Giving or receiving a gayboy glory-hole blowjob in a Chick-fil-a bathroom stall.
Dan Cathy sure delivers the best chick-fil-atio in his restaurants' bathrooms--except on Sunday.

The act of a man receiving fellatio in a Chick-fil-A restaurant.
The bathrooms need to be cleaned. Looks like a lot of Chick-fil-Atio went down.

The act of performing fellatio in a Chick-Fil-A parking lot.
Wow, chick-fil-atio has been on the rise lately. Nowadays it seems like you can't order some waffle fries without stumbling upon a whole crowd of young men orally pleasuring one another!
