Conveniently Bipolar 

When the symptoms of an individual's bipolar disorder only seems to interfere in their life when it is to the afflicted person's benefit.

Bill is completely sane when asking friends to lend him money, but becomes conveniently bipolar when it's time to repay them.

top bipolar 

Person in highest position of power, in government or business, whose mood swings cause great havoc on the economy and the life of large number of people.

Typical of the entertainment industry and oil rich third world countries.

What´s the programming strategy for next season? Dunno... depends on our top bipolar executive.
Why the economy of rich oil countries sucks so absurdly? Oh... they always manage to elect top bipolar presidents.

Naomi: Dood, he clearly suffers from COVID-Induced Bipolar Disorder (CIBD)!
