Kidology (British, informal)

The art of deception; calculated bluffing.

(Particularly used in sports writing, especially soccer.)

"The goalkeeper's hand-waving gesture was a piece of kidology designed to confuse the oncoming player."

"Kidology is an essential skill in many card games."

Just being picky, but shouldn't this mean the study of joking around, teasing? That's what the -ology ending usually means, no?

Or child psych or the study of young goats?

You're kidding, no?
