Describes a blonde hair woman who has afternoon tea and doesn't like when something isn't "ship and shape," will definitely let you know about everything that seems out of place. Otherwise, used to describe people in public who deliberately flip the fuck out when something isn't what they expected. Over-exaggerated emotions towards service desk people, checkout clerks or fast food workers.
Example 1: Karen says that the guy at the oil shop was trying to slash her tires when he dropped his tool. He got oil on the car door when he got up to grab something else. Karen asked Wanda over a cup of tea that afternoon if she shouldn't have gotten a free car wash too, truly exasperated.

Example 2: Karen buys a phone from Verizon and brings it into Walmart for a repair, then flies off the handle at the clerk there when they can't help them. Karen ends up having wasted her entire day, then proceeds to take it out on everyone else in the store in a flying fit of rage, or randomly insults someone standing nearby because they look like a jackass.

Innocent bystanders silently think, "Shut up Karen."

Get the Shut up Karen mug.
When your office mate has a reactive condition to everything and makes you wear old, dirty shirts so her symptoms aren't exaggerated by your toxic laundry cleaners, which she attempts to replace with non-toxic, cruelty free drier sheets made with mushroom-based, woven fibers and chamomile tea. Her escalations includes: spitting up in her mouth, dizziness, itchiness, bitchiness, accusatory statements of microwave abuse, fiber discrimination, strawberry bashing and long conversations with air filter suppliers in the Philippines. Only to be followed by vaccination indictments and promises that you will die of cancer.
Shut the hell up Karen.
