The
act of surfing the
internet searching for abnormal, bizarre and sick human activities, mostly sexual related (for example docking, fooping, dutch rudder, etc.), while controlling the keyboard with one hand and
juggling the willy with the other hand. Wietering is the literal translation for the Dutch word "Pieteren", because in Dutch a willy is commonly referred to as a "Piet".

Katie: I only
see one hand on his keyboard, so he's probably wietering.
