the process of rolling a rather large joint, and then most likely toking it.
Hey, you roll any fattys lately??

To drive a steamroller over a fairly-to-exceptionally fat person, preferably male.
MJ: Yo man, you wanna go roll a fatty?

Kevin: Yeah, who you wanna do, Blake?!

MJ: Nah, too easy.
To have sex at both ends with a fat woman, by first fucking her up the ass, then rolling her over and fucking her up her clit.
I don't know what came over me. She was a bit overweight which turned me off, but by the time she was done sucking my cock, I got so horny that I started rolling a fatty.
