To commit Theydon Bois is to insert well-known and somewhat tired cultural catchphrases into everyday conversation.

The worst kind of Theydon Bois is that which is unrepentant - as if the teller actually believes they are telling a joke, rather than the reality of simply repeating someone else's joke. A parrot can do that.

The worst offenders are typically those that still think Little Britain is funny.

Boising (vb) - the colloquial term to describe the passtime that relieves you of friends.
"Am I bovvered that my general conversation is just one long Theydon Bois?"

- "Wassssssssup?"
- "Stop Boising!"
