Hummer: restore your manhood

Just saw a commercial for Hummer where a man checking out at a grocery store with his tofu, and the guy behind him is buying lots of meat. The tofu guy saw that and then saw a magazine with a Hummer on the cover, so then he decided to go to the Hummer dealership to get one. It ended with a slogan "Hummer: restore your manhood". Okay, so what's the point this commercial is making here? Hummers are only for guys that are insecure about their manhood? Real men don't need Hummers. I guess all the stereotype about Hummers are actually true.
