The situational One under:
Adam and his girlfriend are sitting down to dinner at the local pub accompanied by a notorious "
One upper", the "One upper" notices
Adam's girlfriend is carrying around
a Kate Spade. He says, "Is that a Kate Spade?", asking this assuming that it is and wanting to make up a story that he bought his girlfriend, or his "one" girlfriend ("One uppers" often claim multiple hot girlfriends depending on who they are around) 2 Kate Spades and probably a real Gucci bag or two...who the fuck knows how many...anyway, instead of "Yes, it is a Kate Spade." She replies, "No, it's a fake one."
This response stumps the "One upper". How does one "one up" that? He's been "one-undered"!
