Every time I read that someone "toots" their PV, I immediately think of making a toot sound like a small train. It drives me crazy, too!
I was also raised that a toot is a small, embarrassing fart. My family are Yoopers (from da UP in MI), where you're proud of being able to fart like a manly man. It's even more impressive if your a woman. My family may be considered rednecks, but I'd rather have that than a bunch of up-tight, nose-in-the-air people.
Oops, sorry for the rant.
