Week or two after move in when they're all encouraging each other as new friends to get out and explore and live college life.
If you're an upperclassman though just make friends with some gaggle of freshman girls by 'helping them move in' or 'showing them cool bars/parties'.
Y'know when you see some shitty Junior or Senior frat guy/loser with his harem of little freshman idiot drunken foids following him to bars? Be that guy.
