When someone acts tough through text messages, but, when they run into you, they run away.
Joe: Roger keeps sending me these texts on my phone saying he's gonna whoop my ass when he sees me.

Dave: He tried to do that to me one time. I ran into him at the gas station and called him out, he got into his car and took off real quick. Don't worry about him, he ain't nothing but a thumb thug!

Someone who talks mad shit online, without the intention or means to back it up in person.
I wrote a post on facebook, and a thumb thug came by talking shit.
