It seems that everyone else can see whats going on, but not the two people actually involved.
You see, that friendship doesnt work. They end up liking each other, just maybe not at the same time. This kind of relationship kills people.
Guys and girls can never be "friends".
also potential boy friend or boy toy.
Nick:where's the fucker.
*10 min later*
Nick: he is in the hospital, have some candy. *hug*
see also galfriend.
Mary: "No, he's just my guyfriend."
Yet it is painfull, it can mean your not enough of a manwhore. Depending on the girl and who you are, you may create a close relationship.
boy: i know, but i kinda want to be your boyfriend
girl: o well i guess we could try that
