That guy over there! Yeah that one. Called Liam. Yeah he's a dick head
Someone who doesn't fully posses the necessary qualities to be a full on dick head. Only slightly.
1:That bitch just shouted at me across the restaurant! Wow, she's slightly dick headed!
2: He ordered me around like he pays my bills. What a slight dick head!
when one has a nasty hangover and his/her head feels big like it's going to explode.
Shit , I got so drunk last night that I got a dick tracey head this morning.
