Femtillion 

A severely large number equal to three quadrillion and three zeros or 10^3,000,000,000,000,003. The term was coined by Jonathan Bowers.

"If nanillion is the billionth number ending in '-illion' and picillion is the trillionth number ending in '-illion', then what do we call the quadrillionth number ending in '-illion'?"
"A femtillion."

famillion 

A family of -illions, it can be millions, billions, zillions, any illion family. The hugest amount of whatever it is you’re talking about.

A lot x 10000000 = less than a famillion

It’s so hot it’s like a famillion degrees.
