what does this lyric mean?

the last sentence of Candyman's lyric

Jane lost her grip and a down she fell : I understand this she fell down


Squared herself away as she let out a yell : wat does this mean?

and also wat does this mean:
He's a one stop shop, makes my cherry pop

I know it's a metaphor, but what does cherry pop exactly mean here?

To square your shoulders is to make yourself ready for adversity, and to be squared away is to put right, get everything taken care of. That lyric is a little unusual so I'm not sure which one they mean.

To pop a cherry is to relieve someone of their virginity. (If you popped a real cherry, red juice would run, right? You get the picture.)
