A desperate, last second attempt made by an individual at a bar, or party, who has not secured any coital relations for the evening. The individual drinks past his limit, then stands in front of the bar, or party, and vomits all over the place. This is an attempt to gain sympathy from a passing female individual, who will then take the individual back to his house or her house, where the gentleman will have a chance of making sex to the woman.
Larry: "How do you keep getting so shit-faced, yet still manage to make sex to the women?"
Bill: "Dude, its easy! You got to go chummin' for chicks!"
