Suitable for use when acting like a clueless foreigner. Must be said in funny accent. Bound to be a sitcom catchprase one day.

Similar in nature to, and a combination of, the mohawk and fauxhawk, the I-dunno-hawk is a hairstyle donned by indecisive dullards the world around. It consists of a small tuft of hair which is gelled in an upwards fashion and is situated from the frontal to the occipital region of one's head. This protruding portion of hair is slightly longer than the sides of the head which look like a scruffy, grown-out buzz-cut.
Martin: "wow check out the i-dunno-hawk on this guy! did he wuss out when attempting to shave a real mohawk or is he just lazy (high) and let his mohawk grow out?"

Aaron: "yeah, i dunno..yikes - what a ginormous tool."

Yeah = yes a) I understand the question, b) it was me, c) i might agree with what you are saying. Nah = No a) I don't think thats right, b) it was not me, c) there is no useful information i can give you, d)come to think of it, maybe i don't agree with you. I dunno = I'd like to put in a disclaimer and nullify anything I just said. Non committal. Common in Australia.

When someone ask you a question but you don’t know the answer. It’s basically I don’t know but saying it faster.
