A Panda in the Grotto, as mentioned in American Pie Beta House, is a threesome in the pool with a black girl and a white girl. It's gotta be rough though because you gotta remeber, Pandas look cute but they're still big bears.
Hey, dude wht's that scratch on your face from?

Oh, I had panda in the grotto last night. It was sweet but I am worn out!!
