hit my phone up 

'Hit my phone up' used only by people called Justin Bieber in songs. It simply means 'hit me up' or even more simply 'call me' or 'text me on my mobile telephone' but that wouldn't cut it as a lyric in his song.

Friend 1: 'Hey do you fancy going out tonight?'
Friend 2: 'yeah sure hit my phone up whenever you're ready'
