n. (Flexee-cookie)
Is a metephortic "cookie" which one "eats" in order to become more fun, easy-going and less stick-in-the-muddish.

When an uptight, wet-blanket is being difficult and others are becoming annoyed by their crappy antics they need to eat a Flexie-Cookie to get back to being awesome.

An imaginative cookie that helps you poop out that giant stick up your ass.

Fun Girl: Somebody needs to eat a flexi-cookie!

Fun Girl: We're going about 10 minutes late.

Fun Girl: Katie, do you need to eat a Flexie-Cookie?

Slang among nurses for sexual activity with a man having a reflexogenic erection, hence flexy. A reflexogenic erection is a form of unwanted erection of the male penis, that occurs when blood pressure changes in the abdomen, rather than by sexual arousal; It can be induced in a male by applying pressure to the lower abdomen, as in cases of forced sex/rape by females upon a male.

Reflexogenic erections are common among males who are paralysed and/or have spinal injuries.
