technically from a myspace bulletin chain-letter. taco: some nice thing of yours, could be a gf/bf, or winning a game. basically means you lost something, not an item though.
"That bitch stole my taco!"
"Oh no she did not."
"Hellz no. That be my taco. Nobody steals my taco."
a variation of the florida taco-- when you cum into a pelican's mouth and mix up your semen with the fish guts located in the pelican's mouth pouch/sack, then squirt it into a vagina and eat it out of the vagina, then you shit on a bigcorn tortilla and puke up the fish/semen/vaginal secretions, then roll it all up into a big soft taco and feed it to a baby.
