A tornado of smoke created by inhaling smoke from a pipe,
joint, etc., exhaling it onto a flat surface in a room with no
air circulating, and lifting your hand swiftly, vertically through the smoke (like a reverse karate
chop) from the surface. If you do it right, at least one toke-nado is formed.

Chop! Woooooah mayne, I blew out so much smoke on the
table, my toke-nado looked like a tiny
hurricane. Yay weed!
