a compliment that I heard about you that I offer to trade for a compliment you have heard about me; can be redeemed at a later date or used as an installment for the future (as in, when someone hears something nice about you, if you have given them a trade-last, they are bound to tell you the compliment you received but weren't around to receive it)\n> Me: "Hey! I heard Peggy thought your butt looked great in those jeans."\n> You: "Wow, really? That's awesome!"\n> Me: "Yeah, that's a trade last, so now you have to tell me next time someone says something good about me."\n> You: You got it!\n> (six months later)\n> You: "Hey! I heard Peggy thought your butt looked great in those jeans."\n> Me: "Wow, really?"\n> You: "Yeah! That Peggy sure is obsessed with butts."\n> Me: "She's not very discerning, either."\n
