Nice find by "ask a French guy".
Even with my schoolboy and tourist French I got the joke quickly. "Bites" is French slang for "Willies". The French guy above has a few grammarian comments that says the headline copy, considered as all English doesn't have the joke. But as a hybrid French/English line it reads:
"Small Willies. Big Compliments."
My money is on it being clever ad copy.
