Beaverboard (also beaver board) is a light wood-like building material, formed of wood fibre compressed into sheets. It was originally a trademark.[1] It has occasionally been used as a canvas by artists; most famously, the iconic painting "American Gothic" by Grant Wood is painted on a beaverboard panel.
Based off of The Zoo Story by Edward Albee, Beaver Boarding is an act.vb. where one decides to purposefully pluck out their eyebrows with the concentration of a Buddhist while wearing a kimono in a laughably small room.
