Get the Thomas it up mug.
To do something incredibly stupid, repeatedly. Usually involves an action that is more harmful to yourself than others. Esp when involves lying.
I tried to help him out after his girlfriend kicked him out, but he thomas-upped and I had to bail him out of jail.

She was all over him, but he thomas'd it up and went home alone!

I invited him over for a drink, but he thomas'd me and I had to call the cops.
