If we notice them and we think they're good looking, my friends and I just make a comment like "that guy was really cute/hot!" or pick out a feature that really stood out that we liked or something like that, then we go back to talking about whatever it was we were talking about before.
Definitely depends on what friends I am with and how attractive that guy is. We always make a comment on his attractiveness and say how we wish we had the guts to approach him, and if the guy is really attractive one of us usually comment on getting him into bed ;) But that's about it! :)
Only the boys that pass by if they are hot, or look our way. Usually makeup, clothes, planning the next shopping trip. How to form that plan to get that guy to like you and typically, the friend who you 'luuvvv' but she posses you off so bad, such a bitch, so jealous but you lovve her!
Not really occasionally only the boy crazy ones but the others just there crushes/boy friends, family, school, other girls, music, movies, and the interests they share, and other good times. If they talk about guys they would talk about what they like one them like me I notice eyes but that's just me and my crew
