Internet slang often makes familiar ideas shorter and more expressive.
Instead of saying:

Because of this, cook became a useful way to react to someone’s ideas, skills, or performance.
Is Cook Slang Appropriate at Work?
Cook slang is mainly casual, so it is not the best choice for formal workplace communication.
In a relaxed team chat, someone might say:
“Let her cook.”
If everyone understands the expression, it may be perfectly fine.

Instead of:
“The team is cooking.”
you could write:
“The team is making strong progress.”
This keeps the message professional and clear.
