I gotta say, a lot of those things probably aren't intended to attract the opposite sex - it's just a guy thing (no, I'm not trying to condone any of those actions). It's like why women own 30 pairs of shoes or prefer Coach handbags - things that certainly don't go that far in getting a date with a guy, but are more so to impress other females. For a guy to have a boomin' stereo system in their car is more so to amuse other dudes, but I think we all know that the amount of bass or decibels isn't going to entice any women to want a ride, and we certainly know that if we're giving a ride to any lady, the volume immediately goes down to 3, anyway.
Uh, in regards to No. 5 on that list above (testicles on the truck)... What the ?? I've not seen nor heard about this ritual, who the heck is doing that sort of thing? Bizarre.
