I would say koozies, cigars, cheap sunglasses ( i notice guys like wearing aviators or sunglasses from movies they like), shot glasses, little bottles of tequila, or condoms.
~Random things I've noticed guys like:
1. the gold bond powder
2. nose hair clippers
3. weird hair wax to style their hair
4. rogaine that you spread throughout your hair and you can get over the counter. a lot of guys are really sensitive about losing their hair
5. at weddings i always see guys looking for shoe shine. so random.
6. t-shirts that say dumb things.
