The action of placing one's penis in between the sweaty flab pockets in a woman's stomach, making the shape of a taco. Sometimes the smell of the sweat from the flab will mix with the beaty swollocks, and one might therefore feel a distinctive smell of ass wine hanging in the air.
Me: "Hey man she gave me such a lovely sweaty taco last night."
Rob: "Wow! How did it feel?!"
Me: ''It was a bit like shoving my penis in between two pieces of soggy sweaty bread!"
Rob: "Sweet I might go home and try that with the Mrs."
Me: "Yeah go for it. You should be careful though because sometimes the smell from you ball came mix with the sweat from her flab and the end aroma wont be pleasant."
