loudly decree an open challenge

Like a good pro wrestler, you know how to play to your audience and also utilize the attention naturally being thrown your way (good or bad). Mimi has a flare for the dramatic, so you decide it's best to keep on as bold and over-the-top as possible.

*CLAP CLAP CLAP* You clap your hands in an ostentatious show, clearing your throat and addressing everyone around you. "Attention, attention! Lovely ladies of the Delta Delta sorority, bros and broskis of the Kappa Sigmas. 'Tis time for games and merriment. Tonight, the lovely Miss Mimi and myself do wish to partake in the Pong of Beer, against all those able and hopeful to do so! Come one, come all!"

Mimi snickers as you finish your speech. Some of the Delta Delta girls look at you bizarrely until they see that you're along with the fine Asian.
