I just wanted to share these words with everyone:

1- Pat down:
to touch someone’s clothes in order to check whether they are carrying something such as a weapon or illegal drugs, for example at an airport
A woman was brought over to pat me down.
Synonym would be to FRISK or FRISK DOWN.

2- Hash key
One of the keys on a telephone keypad. Its sign is “#”, also known as the number sign & as the pound sign.
