Do you like it if a girl makes the first move?

I want to go out with this guy but he hasn't asked me yet. I'm tired of waiting. Everytime I see him I get erflies I've never felt this way before. Should I ask him out jokingly? If he says yes tel him I was serious? Or just be straightforward? It's at the point where I'm tired of flirting and I think he knows.( I blew him off on Monday) also I won't see him for 3 days. What should I say to him when I see him. I was kinda mean to him the last time I saw him. I'm 21 he'S 24
