rare cat 

A strange individual, who will often be highly opinionated with crazy out there ideas on the world, these individuals can often be found telling those less informed cretins any and every specific detail about all subjects (they are after all always better informed than you), they can often be spotted with strange hipster goatees and ill fitting leather jackets

Yeh that guy at the bar last night spouting the racist diatribe was a rare cat.

Pronounced 'rare cat', it refers to a female so beautiful that she is deemed a rarity. Worth leaving your wife for probably.

''Check out the rack on that rarecat''

''Did you pull a rarecat last night?''
