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.
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
