Squishable Flocked Christmas Tree

What is flocking exactly, when used as a noun? We're not entirely certain, but it's pretty and fancy and looks great on a Christmas tree...so here is a fancy flocked Christmas tree in bigg full-sized form! Perhaps it's even fancier than its smaller predecessor, if I do say so myself! I'm saying so myself.
