Overheard today in my room

This kid was in a chat room today, and this is the last time i let them in chat rooms. Well he was in a chat room, and he is speaking out loud what is being typed on the screen. “Hi, joseph….how are you?”, “I am fine”, “Do you give head?.” Joseph looks over to his friend, what does that mean, give head? I laugh and say no more chat room in my room, EVER.
