Girls think it's lame when guys give flowers and chocolates. Apparently, it shows no imagination, and she'd rather guys listen to things she says she wants.
The Dreaded Pop-In
When guys stop by unexpectedly to say "hi" or hang out, it's lame. One exception - when he stops by to say, "Hey, want to go to Paris?"
Buying Cheesy Lingerie
Simple rule here - guy should buy things the girl would feel comfortable in -- not just what he wants to see.
Being Overly Sensitive
We all know about this one -- when guys get too sappy, and write too many love letters and poems, they sound too needy and weak. It's not fair, but that's the way it goes.
