An Island in Lake Washington that can be compared to Bellevue with its large population of extremely spoiled, naive, rich, pussy guys as well as (usually) hot, extremely spoiled, naive, rich, bitchy, stuck-up girls. (can be used as an adjective is some cases)
Noun, I would hate to live on Mercer Island (or in Bellevue) because everyone is fake and are extremely superficial.

Adjective, 'His response to seeing an African American man at the cash register at the restaurant was extremely Mercer Island as his hands started to sweat and walked quickly past the restaurant with his hand covering his wallet.
 
23.
A high school that has a long standing rivalry with Bellevue High, a school with a better football team, better academics, better location, better parties and better people. Unfortunately Mercer Island continues to try to compete with it and so continues to be publicly humiliated. Most people who live on the island go to Bellevue or Seattle for dining, shopping, or any form of entertainment, since none exists on the island itself.
The people from Mercer Island thought it would be cool to bring a flag to their away game, but it was broken by the home team when the pre-pubescent MI students got too rowdy.
