a personal character trait that is considered detrimental to mental health, due to its association with stress and anxiety. An insecure person may or may not lack their own self-worth, rather they feel overriding doubt that they can pursue a task to its conclusion without moral support. This may be linked to events in the past that have caused them to lose confidence due to negative feedback or ridicule in social or personal circumstances. These criticisms are usually personal in nature. Insecurity is a trait that often precedes an act but it may disappear during its performance and reappear after its completion, as many artists such as Judy Garland would testify.
I feel so insecure about my voice and appearance before I go on stage but as soon as I am in front of an audience I come alive.

An insecure person is someone who just feels like they need to compare themselves to others. They think that if they tell themselves that they are good enough that it will come true. What they don't know is that they are already good enough. They will see themselves as less than perfect, and hate themselves for it. If you or a friend is like this, know that you or them are amazing the way they are. If they see it or not.

When you feel like you're not good enough, you spend hours trying to look your best. You push people away because you're used to being used and people turning their backs. You lie, not about things to seem cool but you lie about being okay. Even if asked repeatedly you still say "youre fine " . people of all ages can suffer with it. And they tend to be the people who are the most caring.
Boy: gosh why she so timid
Girl: she's not timid, she's insecure

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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
