A phrase used in a south park episode where Mr. or Ms. Garrison explored being a lesbian. Garrison was in bed with another woman "scissoring" (in which two women inter-lock each others legs for sexual arrousal). it is at this time that Garrison becomes excited and says "Oh yeah scissor me timbers!!!".
Lesbian: "I haven't gotten a piece of ass in a while I really wish somebody would scissor me timbers."
