Going down the list
25. What "club"? You mean the one I'm playing at? FU
24. Sure. I'm not sure what TapOut is, but I see it a lot on pick up trucks, so I probably wasn't interested in the first place.
23. I'll short hand whatever the hell I want. STFU
22. I have a better idea; don't golf.
21. A LOT of guys of different ages from Jr High up have piercings today. FU
20. Only if women get rid of their stupid Honor Student and "here's my family" bumper stickers first.
19. The graphic tees are out. That's not an age thing.
18. I have a great reason for bumping my music; I like it. Don't like it? EAD!
17. Knit caps are stupid for any man, of any age, that isn't actively skying, walking in a place where there is snow, or hunting white whales. Teens look just a stupid in them as grown men.
16. NO ONE over the age of 10 should watch Pro Wrestling.
15. Where a person lives is none of anyone else's business. FU
14. You can, absolutely, positively, 100% smoke my pole. I've loved metal since I was a teen and have grown with the genre as it has changed. It beats the daylights out of any of the crap on the radio, so I see no reason to stop listening to it. FU
13. Drinking games are lame for all people of all ages. If you want to drink, just shut up and drink. If you have to find ways to tease yourself with it you are an alcoholic.
12. Still having a flip phone isn't a sign of age, its a sign of intense cheapness and/or phobia about technology.
11. Why are you checking out my wallet? Its a #$&ing wallet, not a fashion statement.
10. I will capitulate that choreographed handshakes are a teen thing, and should stay there.
9. No one should wear flat brimmed hats.
8. If I'm just going somewhere for the weekend, I'm not going to dig out my luggage. When I get on a plane, my carry on is a duffel bag. FU
7. Horns up \m/
6. See 13.
5. Aren't online arguments as lame as online lists

4. Who the hell irons anything anymore? My wife doesn't know how to use one on anything besides crafts. Isn't everything "wrinkle free?" If you bought something that needs ironing you're a dolt.
3. There are some 30+ guys that will destroy you at paintball! BTW Paintball > Golf.
2. Lifted trucks are stupid period.
1. How about using any movie poster to decorate your house?
