There are so many girls walking around on campus. Do you approach direct or indirect + how do you get them to stop walking?

Here are some openers that might work for a campus:

"Excuse me.. do you know what time the dining hall closes?" (you can switch dining hall out of Library or computer lab)

"Hey.. do you know who won the game last night? I passed out early"

"Hey what time is it? My cell phone is acting weird"

"Hey, have you seen an SPAM on campus? Where is it?"

Or you can go more complimentary:

"Hey.. I really like your style. Its very unquie"

"Hey you look like your in great shape. Do you play a sport?"

"Hey you look like your in great shape. Have you been to the campus gym? I've been meaning to go myself"

Women are smarter than you think... but not as smart as THEY think

Loving those openers. The complimentary might make you look like an AFC esp. if too abrupt but the first few seem like they might work if you can get them to "show you the way"
