semi

Say "semeh" or "semi hot up" or "semi hot"
The primal meaning is when some situation is slightly conspicuous but not blatent. It comes from the word hot up which means conspicuous, originated in Tinsley, Sheffield. Pronoced in a northern british(yorkshire)accent.
Also the word is often used when a situation that should perhaps be subtle or secrative is really obvious, in which case it is used sarcastically, sometimes as "bare semi".
You've just picked up and ate a sweet from the pick and mix section in a store. You're friend says, "semi"

Two friends in a car at night jump a red light and then notice the car stopped oppisite is a police car. One of them says "semi", the other replies "bare semi".
