It's alright, lovehurts. Everybody needs to fit in and make lots of friends, however, ignore everyone who says be yourself. These people are wrong. Instead, here is my step-by-step guide to becoming the Campus King:
Step 1: Buy several polo shirts.
Step 2: Wear the polo shirts.
Step 3: Make sure the collar is popped up at all times.
Congratulations, you are now popular!
Now for the ladies, because after all, that's what college is all about! Am I right? Huh? Huh?
Step 1: Go to a popular student bar. Sometimes you may need fake ID, what with the wacky American alcohol laws.
Step 2: Find an attractive female student, who is older than you. After all, you're too good for freshman girls!
Step 3: Tell her you're going to be a doctor.
Step 4: Try to cop a feel, before being shrugged off. Bonus points if you earn a slap.
Step 5: Vomit on your shoes before stumbling back home.
Success! You are now the University's #1 Cassanova!
