He didn't name it "Labia" or "Clitoris", he named it after a product that females use for hygienic purposes. I can't really think of a particular brand of male-genital-hygiene products off the top of my head (that aren't also used in other areas, ie: hair trimmers or washes), so I went with something as similar as I could that served a single unique purpose.
I'm not saying I'd see a product named Jock Strap and say "Wow, that's a great name!". My point was, the initial shock value of the name wore off once I realized I wasn't in the third grade anymore and it was just the name of a product that ~50% of the worlds population makes use of on a regular basis. A shock value that would not have been there for me had the name been something like Jock Strap, which would be a product that I'd be more comfortable making quips and jokes about.
Also, "Flower" and "Butterfly" are feminine words now?
