rubber check
A check that is going to be returned for non-suffecent funds
All that woman writes are rubber checks, I'd only take cash from her
rubber check
a check that can't be cashed because not enough money is on deposit (because if one did so it would bounce)
I found a rubber check in his room.
rubber check
Da "pre-fun" inspection between da legs of a lust-crazed stud dat a teenage girl's parent performs to see if said eager male lover is wearing a condom.
Unless you're gonna stay and actually monitor da vigorous bouncy-bouncy between your "little pumpkin" and her main squeeze, doing a "rubber check" beforehand would be about as "worthless" as a latex-sheet financial instrument, since da warm-and-moist-love-tunnel-craving guy could just "hop off da Trojan horse's saddle" --- i.e., slip his love-pipe out of its "raincoat" --- just as soon as yer back is turned.
rubber check
Where a gal promises to "pay" you for a favor by spreading her legs for you afterwards, but then unexpectedly insists that you wear a condom, which of course drastically reduces the pleasure of the act and thus largely negates any true value of said "payment".
Any time that a "willing" chick offers me sex in exchange for my assistance, I always make sure to first ask her if she's gonna let me "do it bareback" before I decide whether or not to bust my ass for her --- oh, I might still help her out even if she wants me to use protection, of course, but I still like to know what I'll be actually getting out of da deal --- I've gotten too many rubber checks in da past!
I'll forge a rubber check for you
What you snortingly/contemptuously tell someone who irrelevantly asks to be paid for something that he should let you have for free, such as an item that he'd already discarded. The joke is that said financial instrument would be DOUBLY worthless --- not only would it be a phony check, but the written info on it would be counterfeit, as well. :P
A humorous-natured local woman gigglingly asked me if I'd slip her a few bucks for some old chipped enamel saucepans that I'd salvaged from her curbside trash-pile, so I made a face at her and agreeably responded, "Sure thing --- I'll forge a rubber check for you for five dollars!"
