"Calluming" is a term from the game World of Warcraft to describe the discriminating of one publicly in the middle of Dalaran, or in a random PuG over their spec, enchant, and gem choices, resulting in humiliation of that player. The term was named after a certain person named Callum, due to his regular 'calluming'.
Man, that was a calluming and a half!
