I still use "fuckbeans" (from Jay and Silent Bob Strike Back) on occasion.

If my life was a movie, someone would be able to make a 10-hour youtube video of me saying "for real" and "for sure".

I say "for real" way too much. I think it's slowly replacing my normal vocabulary. For real.

There are a whole bunch of Scottish ones as Fetcher outlined in the OP. Only a few creep into my regular vocabulary.
'Sound' - cool
'Mad wae it' or 'mwi' - my personal favourite 'drunk' synonym
'Hoaching' - busy, crowded

For real.

"Groovy" is also part of my vocabulary.

^^^^ yeah me too and Fab :p:

whenever someone says something preposterous, my reaction is either "I'm so sure" or "don't even".

I never used to say those things before I came to the west coast.

Sherppin'- Avoiding somone or somethin.

Heard this for the first time the other day, was confused. Supposedly it's not so uncommon in Washington? S'fun to say so I'll work it in if it's real

I don't think I've ever heard that term.

I've lived in Washington my whole life and I can say that you posting that word is the first time i've ever heard of it.
