promisery note

A contract that typically gives moderate-to-acute grief to one or both parties.

Lending money is never a good idea, but it can be especially painful between family and friends, since their promisery notes can create tension in their amicable feelings if things do not proceed exactly as planned.

promiscory note 

An agreement to spread your legs "freely" for someone who loans you money if you are unable to repay said loan after a designated length of time.

Da prob with a promiscory note, of course, is dat you have no guarantee dat da chick to whom you lent da money will keep her word about "letting you milk her", any more than you could count on her paying you back da money she borrowed.
