You can still pack a punch with swearing, you just gotta get creative about it.

Swearing is to language what capsaicin is to food. It's not required, in some circumstances it makes things worse, but in many other it would be a real shame to deprive oneself of it, especially for a reason as stupid as "but I'm going to increase my tolerance". So fucking what? It's not heroin, shit's not going to put you into cardiac arrest if you take too much.
