Chickdar

a semi - conscious part of the occipital lobe which is active in a dudes peripheral vision at all times. This neurological phenomena becomes apparent in males from the beginning of puberty and lasts until death.

a chickdar allows the male to instinctively spot an attractive and suitable partner of the opposite sex, known commonly as " a hot chick".

the chickdar could also be thought of as a third eye, i.e. The post pubescent male will usually always know when an attractive member of the opposite sex is near prior to observing them in his conscious field of vision

Dude! did she register on your chickdar?
