any statement that can be taken out of context in a sexual way. usually yelled out.
a friend when describing her favorite type of purse, said very loudly, "i like the big, black ones!" (so in response we say either just "twinkie!" or "that's a twinkie!"); even just simple statements like, "i'm easy," i'm flexible," or "i'm open," could be twinkies;" another example, my friend ben, arriving late just behind another group of tardy girls said: "i'm glad you came right before i did," and the girls responded "twinkie! that's the way it should be."
