so i was tweeting and I see this guy I know on twitter and he tweeted saying "im still up" and i commented "go to bed" ( playfully)

and he was like "go eat or something " and then i was like " why are you always saying a fat joke or something " and he was like " because you on my tweets like im tweeting about how much i love you or sumn lol you go to bed im older than you anyway " what does that last tweet suppose to mean i dont understand?

He was being really flirty if you like him try talking to him more. Ok please help me with my question it's killing me.
