Does swearing up a storm act as bug repellent?

Blurting out a string of unrelenting profanities (that would be sure to make your local sailor blush and maybe your mom disown you) does absolutely nothing against the evil little buggers that are called no-see-ums. I can personally vouch for that one and I have a pretty extensive vocabulary of profanities. But man oh man does it feel great to smear their little bug guts all over whatever part they happened to be biting at the time. After a week out and about we are covered in welts that itch like nobodys business. David got plenty of bites, but it seems I got more. Why must I taste so good I ask?!
