What does "suit up" mean?

[matt7777]

Girl texted me this, no idea what it means.

[Hideous]

I think it means to dress up or get ready for something.

Get dressed in an adequate fashion...?

Are you guys in a relationship or FWB

Were I live oit has two meanings,
To put a condom on, I doubt she means that, and if she does your lucky.
It can also mean just get ready to go out somewhere, possibaly to a fancy or nice location.

Or she's secretly a superhero who derives all of her powers from her costume taking him on a journey to save a distant alien planet from imminent doom.

No? I didn't think so. :P
