If somebody is talking about something different than what you are talking about. It usually implies that if you continue to "talk tacos" while I am trying to push across a certain agenda, violence
will ensue. Originated as a response to somebody suggesting that because there was no halal cart open (for chicken and rice),
late on a Saturday night, a nearby
taco cart would have to suffice.
Thomas: Yo, I really want some chicken and rice, we should go down to 53rd and 6th.
Erik: I need some cnr.
Eric Weiser: Yeah, my mom won't let me stay out that
late we should just
get tacos at the
cart on 96th and bway.
Erik: He's TALKIN' TACOS.
