Jackson explained that the "descriptive and encompassing word" can change in meaning depending on how it's used but said he mostly uses it as a "term of endearment."
Unfortunately for Jackson, he was unable to utilize his favorite word while recording the voice for Frozone in "The Incredibles 2," but Ellen once again gave the 69-year-old actor the go-ahead during an epic game of 5-Second Rule.
Q: Name three curse words you say the most.
Jackson: "Shit, (inaudible but sounds like the male chicken?) and motherf-cker."
Q: Name three celebrities you'd want to go on a road trip with.
Ellen: "Tiffany Haddish, Portia de Rossi and Jennifer Lopez."
Q: Name three things you always forget.
Jackson: "My name, my address and my daughter's name."
"You don't forget your name!" Ellen reprimanded.
"I'm 70 years old! I forget all kinds of shit!" Jackson fired back.
