first-up 

First of all, before anything else, on the very top of your to-do list.

First-up, you need to make sure you have enough money before thinking about starting your own business.

first break up 

your first breakup will be the hardest to get over. it will hurt the most and will have you questioning yourself everyday. thinking “were they really the one” or “why don’t they love me”. your first breakup will drive you crazy, it will tear your heart into a million pieces. every song you hear and every object you see will some how remind you of them. you will cry. a lot. it will be tough

your first break up will have you crying in your bed for a week wearing sweatpants

Fuck Up of the First Order 

1) Adjective - The ultimate mistake which ends with disastrous consequences, usually involving multiple parties which were not, directly, involved in the incident. Usually, it starts with a minor, low level, bad decision.
2) Noun - A person who commits the "ultimate" mistake.

The introduction of the Africanized Bee in Brazil in 1957 created consequences that spanned across continents and devastated ecosystems. This is prime example of a "fuck up of the first order".

The person who actually released the bees, or setup the conditions where the bees where released, is also nown as a "fuck up of the first order".
