home game penalty for cussing - what to do?

[CrazyN8]

Just looking for help with a fair way to penalize people in home tourneys.

History:
I take issue with the use of G.D. This is well know among my friends. Most of them try to avoid using it but it slips, I understand. I don't blow up or get all pissed about a few slips. However, one individual in particular seems to try to use it as much as he can or push the envelope as hard as he can - just to be an ass. It doesn't mess my game up but it bothers me that someone (an adult) would act like this....thus:

I am thinking of enaacting a no cussing rule in our home tourneys (yeah, I know, you don't have to say it). This way seems fairer. All cuss words are banned - which effets me.

My question: What is the best way to penalize for this?

1st a warning then: sit out a certain amount of time, take a certain number of chips from them and put it in the next pot, or other?

If time, how long?

If chips, how many? X# of BBs?
