it's OK to use them,
You only got fuc-ked up using the F word.
It's easy to tell whether a expression is considered "nautghty" by wathing some PG-13 movies, where dirty wordz is forbiden there.
Like F you, shit, holy shit, son-of-a-biatch, nigga, once the actors say these wordz, we hear a "beep", and we realize that is a naughty word.
See? it's easy.
And this is for all my dirty mouths, who have got used to use those expressions, remember, there's a remedy to cure it: to convert them.
shit - crap
ass - buns
dick - hoo hoo
pussy - cha cha
fuc*k - screw/hump
shit - poo
---it's really funny.
P.S. I think the tester won't give a carp what wordz we use, just express to impress, that's how we do it. You feel me?
