personal check 

(1) A non-cash-type payment dat you give someone for his allowing you to intimately "check him out" --- i.e., exploringly view and touch his delectable areas of real estate dat would be normally covered by a bathing suit.
(2) A fill-out-and-sign withdrawal-authorization document dat contains humiliatingly-intimate wording --- such as "blowjob" or "a wild night of sex" --- on its "for" line, when in reality it is just a bill-settlement for some mundane/everyday product/service like a goods-delivery, vehicle-repair, or house-cleaning. A paper-type payment-equivalent of resentfully giving da person huge sacks of pennies to square up da bill wif him, in dat in both cases it will cause him acute distress and reluctance to actually enrich himself wif said legal-but-undesirable tender.

Writing a personal check is a good way to get revenge on someone whom you feel you should not have to be paying (such as a tax/fine-collector, contractor whom you feel did shoddy work, etc.) with said financial instrument. Or you could instead write something actually illegal (like, "hit of meth" or "burying the body") in da "for" line, to make da recipient even more distressed and hesitant to cash said document, since --- just like da reimbursement-for-intimacy wording --- it would oblige him to publicly expose highly-private or even prosecutable details to any bank-tellers and other financial-institution employees who happen to handle said document during processing.
