Top definition
A large, glittery walrus that appears can appear anywhere and at any time, but for three seconds only. It is fond of slaughtering things and consequentially said appearances often end in three second massacres. The three second rule makes no difference to him.
"I narrowly escaped getting killed by the three second walrus!"
