Lush (adj)

[mcgillianaire]

1440, "lax, flaccid, soft, tender," from O.Fr. lasche "soft, succulent," from laschier "loosen," from L.L. laxicare "become shaky," related to L. laxare "loosen," from laxus "loose" (see lax). Sense of "luxuriant in growth" is first attested 1610; erroneously applied to colors since 1744.

This is my current favourite British slang word. Urban Dictionary has a decent definition: British slang term to describe something pleasing or desirable. Eg: "that girl is fucking lush" or "i had the most lush milkshake last night". That first example is lush.

I find non-Londoners use it the most and when my North-East mates say it, it rhymes with whoosh. I'm not sure if pappubahry noticed it when we met a few weeks ago, but I find myself pronouncing many words ending in -ush as though it rhymed with whoosh. So cool!
