A general exlamation or adjective. Useful for when more widespread words elude you.
Origins: Kings' Heath, Birmingham / Redditch, Worcestershire. Originally derived from the name 'Adam West,' a prominent local celebrity known to perform street magic and stripteases.
"You're a bit of a swest!"
"Ahh Swest! I just dipped my elbow in that stool sample!"

Two stories of origin:
A couple guys on a chair lift in Vermont making up words combining existing words, in this case "Sweet" and "Best".
And the other possible origin giving 'Swest' a new meaning...
A group of stoners bought the biggest rolling papers they could find, attached several together around a wooden table leg and filled it with greenery. The Joint was named 'Swest'
it replaces words such as cool, sweet, nice, awesome, and a large doobie, joint, gagger, blunt, johnny etc...
