There is no definition because it isn’t a word and never has been. Anyone who believes that there is a word like that is wrong and needs to check his/her vocabulary.
There isnt an example because there is no such word as leniency.
whenever a woman comes to work wearing boner inducing clothing (see: bonerwear), boner leniency is granted to prevent a sexual harassment suit when the offending man is spotted with a boner.
Of course i was offended by his boner, but i deserved it because of my bonerwear... and he deserved some boner leniency.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
