1/ Wear guys clothes


2/ Have that big fat ego of theirs

3/ Think with their pants

4/ To be a guy, you have to be cool and calm in even the most critical situations, just appear casual, like nothing matters - Pei Yi
This is true. Though now why can't that be said of girls? Are we expected to be all like, panicking and running about like headless chickens?

5/ indulge in MANLY sports such as rugby. Beef them up- Angie (friend from Australia)

6/ Be a gentleman
  Ie. Open doors for them, walk them to the door, let them go first, be courteous, etc.

7/ Don’t cry over little things. – Carmen
