"Cowboy Up" is when you are injured or down and the prospect of doing whatever it is you're about to try is so bleak that the best you can hope for is to live through it.

Basically, another way of saying "Shut up and take it like a man" or "Quit your whining." The term is derived from the popular image of cowboys being tough, unflinching, uncomplaining, and hard-working.

The original meaning of "Cowboy Up" was to inform the next bullrider or bucking bronco rider at a rodeo to get ready to ride or "cowboy up". Now it means to stop being a pussy liberal snowflake with your safe spaces and whiny bullshit, grow up and be a man for once in your pathetic life.
Liberal snowflake type: Oh no! Trump won the election! I need to find a safe space to calm down and stop crying.

Real man type: No you need to stop being a pussy and cowboy up!
