Stick with what you know

To be selected; To be chosen

to research and confirm

Now we're talking!

To play dumb

posterior

To get caught up in someone's enthusiasm

crupper

To feel lazy

To have your secrets exposed

Half-finished

to remove one from their position

Imminent danger

Cheese it; Make like a tree and leave; Make like a banana and split

Neverending

enjoying a sumptuous feast

To light a fire under someone's ass

a place of learning

① polish ② study diligently
