You lie like a cheap thai watch

Said in a situation where you do not believe what is being said to you by someone. Cheap thai watches are known to get the time wrong because they are cheaply made. This isn't an insulting or provocative term but a reactionary and conversational term.

Definition first heard in the Medway area, particularly areas of Parkwood and areas of Strood in Kent, England.

"It's wasnt' me, I didn't do that"

"Ha, you lie like a cheap thai watch!"
