Badly lying when your caught lying.

Stop trumpin me I see the lipstick on your collar.
Are you trumpin me about that game? Everyone saw you drop the ball.

Continuing to deceive with blatant falsehoods when you are clearly lying.

Why are you still trumping I can see the cookie crumbs in tour mouth.
Are you trumping me?
You can stop trumping to me I see the lipstick on your collar.
