Contrary to the acronym ‘dtf’, which is used to ask another person if they’d like to have sex, ‘dtfa’ is used to ask your homies if they’d like to go mess around in the neighborhood and get up to some shenanigans, especially at night.
Homie 1: Yo u dtfa tn?
Homie 2: Hell yeah bro I know about a new abandoned construction site
Down to fuck anything that walks. A ridiculously horny mindstate in which someone is willing to have sex with just about anything at anytime, anywhere.
"Dude, you haven't gotten laid in months. You must be DTFATW."
"Of course, I'd even do that 400lb'er over there."
