tmtfb 

its an acronym used in texting. it stands for "text me the fuck back!" it can be used if someone hasn't responded to one of your texts in a long time.

"dude jake hasn't responded to my text and its been four hours"
"just send him another text saying TMTFB!"

*texting conversation*
Katie "Hey whatsup"
John=no response
Katie "TMTFB!"
