An all encompassing term for initiating sexual activity in an upstairs area, typically, but not limited to, a bedroom. It is a conjunction of "Let's go up." Most often used when in a hurry to start slappin' parts, and too lazy to actually pronounce the whole phrase.
Damn, George. You are looking so sexy in those ridiculously colored pants that I am so ready to sgwup.
