Fro me --> put on the tightest shirt you can find - eg. I found this Nike pro-combat dry fit top. Go to the gym, spend 30min-1hr, kick all the other guys' butts on the treadmill, burn 500kcal, sweat like a mofo, and then when you riding the elevator down you bump into this girl who gives you like, then once over 2-3x, smiles, then starts chatting you up. ha ha that feeling is incredible.
You can call me an idiot I don't care. I am vain and I love it.
You know what else is good? I went back to buy another 3 pairs of these because they felt so good - the retail guy sold them to me half price! 18 quid for 3 pairs. Talk about having a good day. He said nothing and I just kept smiling.
