Bard Brain

An aficionado of the works of William Shakespeare of Stratford-on-Avon, England, 1564-1616. Self-explanatory, not meant to denigrate.

Bard brains everywhere will appreciate the local production of Hamlet, from December 16th at the Town Hall.

doody brain

Same thing as a shithead or a fucking moron, either fit very well. One who's head is filled with excrement and cannot make intelligent decisions. A Douche, dildo or jack ass.

My friend Barratt is a fucking doody brain.
