Post-fartum expression 

The sigh of relieve and that silly smile a person has after letting out that gas that has been held in for so long.
Slightly changed term from 'Testees' Ssn1 when Peter lets out a huge fart that he thought was a baby and Ron tells him he's got post-fartum depression. Post-fartum expression is easier to relate to.

gender expression 

Gender expression is exactly what is sounds like it is: the way you express your gender identity. Are you a woman? Wonderful! Does that automatically mean you love dresses and adore cat eyeliner? Nope. There are many ways to express one's gender identity whether heteronormative or gender-non-conforming! Historically, gender expression has been commodified and culturalized, dividing the population into either lipstick-lovin-ladies or motorcycle-muscle-men.

But wait--you pick a gender identity, does that mean your gender expression must conform to that identity at all times??? Hell no! Your gender expression can manifest any way you want it to! It's all up to the individual. Today: femme. Tomorrow: genderfuck.

Remember that gender identity includes, but is not limited to, identities such as 'woman' and 'man,' what would be called cisgender. Genderqueer identities are numerous: there is genderfuck and femme and gender fluid and gender neutral and agender and transgender and many more. For more examples, just go to your facebook page and check out the updates gender identification options (not that this list is entirely inclusive, but it'll provide you with a decent basis!)

Jaquan: Oh, tight. Maybe tomorrow I'll wear a skirt.
Bailey: Hell yeah! Express yoself!

self expression 

1. Personal actions or habits intended to convey, or expose, emotional or intellectual conviction. 2. The act of creating art for the sake of personal gratification. 3. A generalization applied to any action that lacks skill or outside desirability, but is, within it's self, a worthwhile endeavor.
1. It's hard to understand why wearing clothes from Hot Topic is considered self expression, when everyone else is doing the exact same thing. 2. We allow the patients a little time for self expression during arts & crafts; it helps keep them from nutting-up on eachother. 3. It could be said that urban-America is reforming it's self into a more positive environment, by using the art of self expression to cope with all the angst and percieved inequities which once drove it's population to pacify themselves with drugs and crime.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
