Can we "Get Together"?

So I was chopping it up with one of the homies and we got into an insightful discussion about the phrase "can we get together?" Like most things this can have several connotations...it can mean:

Lets go hold hands in the park

Let's study at the library

Go on a nice date

*Oochie Wally Wally Oochie Bang Bang

So he was saying when he makes this type of vague statement he never really knows what the girl wants and I assume he is open for any of the options above. The flip side to this is that when guys make such vague statements why do they get mad when you ask for clarity? Like all we are suppose to say is Yes...and be all knowing when he makes a move cuz he was thinking Oochie Wally Wally...sheesh....lol. So whenever you hear a vague statement like "can we get together"....u better find out what together he is talking about because you never know! Sidenote: Chances are he doesn't know either...lol!
