A phrase that is used mostly as an insult or a warning usually by someone one with a weapon who wants to kick the shit into you maybe because you have insulted them.
some guy: you're a fag
me: dont make me go upside your head

(then if they say ANYTHING you smack them. Or in my case smash them round the face with an old wrench that i 'aquired')

Looking you upside your head means to look at you in a crazy manner due to something that's going on crazy around you due to your allowance.
