Censored word confusion

[Phantasm]

Last night when posting, I noticed that the infinitive and past tense of a particular word (the slang for both "to urinate" and "to anger") was censored but the third person singular present tense (ends in "-es") was not.

I'm a bit curious as to why this particular word is censored in the first place. Despite being one of Carlin's infamous "Seven Words You Can Never Say on Television", it doesn't seem to elicit the same level of disgust in the more non-indulgent groups of society as the others. (Particularly since I've heard this particular word in the "to anger" context on network television recently, while the others still get bleeped.)


(Or maybe I'm just desensitized to such things and the third person singular present tense just needs to be added to the censor list...)
