So I came across this ad for electronic cigarettes, originally from a Rolling Stones magazine. Obviously it's saying that sleeping with an overweight girl is something you should be ashamed of (but you're a man so you aren't, HAHA!). If you think about it, the issue of obesity in all its forms is almost uniformly cut out of advertising, unless it has to do with making you feel like you should improve (oh those never-ending Jenny Craig commercials). But it's certainly not something that is ever joked about, like the "useless husband" stereotype. Actually, overweight guys are kind of acceptable on TV (I'm thinking King of Queens, According to Jim) but you will NEVER see a fat woman with a handsome guy. I hate that fat, immature husband and smoking wife trope.
Is it clever to associate your product with something that men find stereotypically shameful (as seen in all the TV shows EVER)? Maybe they figure that some guys find electric cigs embarassing anyway, since they're a little less manly than the real thing (you would never see Clint Eastwood with an electronic cigarette clamped between his teeth), so may as well try to make it work for the product. I think the message of the ad is something like "Well sure, you'd normally regret sleeping with a "fat chick" but when all is said and done, you still got laid". The marketers are implying that you should do what feels good or is good for you (like smoking an electronic cigarette) regardless of what your friends say.
Still. Does this image really make guys interested in the product at all? I don't really think it would. It's going for humour but I don't think it's the right kind.
