trumping

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.

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.
