I was mid prem game, and at somepoint as i was playing someone typed in the chat as yellow on ct side, (which is me) as I was walking and actively playing, and "I" said something along the lines of "uwu~ I have 700 hours on cs~" or something along the dumbass anime tiktoker lines. Can someone explain how someone typed from ME, mid game?
