Yeah that might not be the best way of asking her out, it may not go over so well you know
If anything you could say
"Hey *insert name here* whats up? hey are you free for dinner tonight?" or
"Hey you want to go see a movie with me this weekend?"
OR, if your really brave
"Hey *insert name here* would you be interested in going out with me sometime? have some dinner and go see a movie? or perhaps we could just go to my place, and you know...touch each other in the bikini area."
...last one might be a little risky though but I bet it will make her Lol
