You need your shit milked.

You need a sort of stress reliever. In this case, a handjob 'offer'.

provocateur: You're having a bad time with work. You need your shit milked.

Recipient: Eeeaaaah! He's touching me!

your head is to gas like your the shit or something

your head is way too big meaning you think everything is abouit you and no one else.

if a girl says "what are you talking about i didnt do that"

and the guy says " lol i thought you were different but your head is to gas like your the shit or something"

then that girl would say "fuck you i dont think i am all that"
