Big/Little Relationship (romantic?)

[DubaiSis]

Be a man. Ask her out on a date. Pick her up at home, bring flowers, pay for dinner, take her home afterwards. Don't try to sleep with her on the first date.

That's how dating is supposed to work. You just have to decide she's worth the risk.

You're making this too complicated. The fraternity isn't the be all and end all of life that you're making the big/little thing out to be.

DubaiSis has it right. Be direct and to the point. You like her - so tell her so and ask if you can take her on a date. You know, "Let's hang out sometime" is ambiguous given the big/little thing. So, make sure you actually ask for a "date" so that she's clear on what you mean. Be up front and acknowledge/discuss the fraternity situation with her if you have to go there.

Good luck.
