The act of buying drinks for attractivegirls, then drinking them yourself or with a bro.
I was out at the bar with my friends and a pair of rather attractive women came up to talk to us. Immediately they ask us to buy them shots. I finally had the chance of a lifetime, so I bought 4 shots, gave 2 to my buddy and we took both shots in front of them. The bartender high-fived us and gave us a free beer. SgtMcHammerfist'ed
