Hell and Fuck(eff) mixed to make a more suitable word of context for those around the vulnerable eared people. ie children, bosses, nuns, priests, old people.
(v) to masturbate and then shower, but tell your friends you are only showering. Thus making them assume that every time you shower it is after you masturbate.
Joe: Yo bro you wanna meet up tonight?
John: Yeah im at home and im gonna heff quickly before i come meet you.
A heff is a sigh but also comes with more meaning, it is another way of saying I don't care/ most mean words, you can say it under your breath or out loud to someone they most likely might not know but its a good way of saying it to a disliked one.
