I suppose they're both vulgar, but one difference is that "pussy" has a derogatory use that "boner" doesn't have.

[nicoburns]

Perhaps, but it also has an entirely innocent use that boner doesn’t. At least here in the UK it’s pretty common to use “pussy” to refer to a cat.

Pussy and boner both have innocent uses. A pussy is a cat, a boner is a silly mistake.

It seems inconsistent that dick (which can refer to a penis, a jerk, or a Richard) is still allowed, if they're worried about derogatory meanings.

Quick edit: DICKS is allowed, DICK is only 4 letters

My wife was returning something from the store Dicks. She needed the receipt and knew it had been emailed to me. A quick check and I didn’t see any such email.

So in all seriousness, while I’m at work on a open floor plain facing computer she asked me to search my spam folder for Dicks.
