I have a friend thats annoying and I texted on his phone because i was bored?

[Danny]

so i just said hi to cute girls on his phone. and then i gave him back the phone but as soon as they said something back he said my first and last name and pretended to be me. The worst part is I was trying to get to know those girls but know they probably think im weired now. This hapened yesterday but im still pretty mad. What should i do? i wanted to get to know those girls. Then his boyfriend started texting the phone and me or zach might be in trouble. i told him to tell it was him but i dont know if he really did say that
