How to use the word 'cock up'?

Can anyone tell me how to use this word, ‘cock up’ with examples?

and what is the part of speech of it?

Thanks!!

It’s like a verb phrase. Just the emphasis form of the original verb. More example, pump up, eat up, drink up,…etc…

hello
my name is tota i want to improve my english thanks

“cock-up” is an informal phrasal verb meaning to spoil something
by making a dumb mistake or doing it badly:

His secretary cocked up his traveling schedule and he’s furious about it.

I’d say this expression is a synonym for “to screw up” (informal as well) :slight_smile:
