4. Hot Willis
A "Hot Willis" is a variation of the "Hot Carl". A Hot Carl is when your partner has a piece of saran wrap over their face and you take a shit right onto the saran wrap, the poo warming their face. The Hot Willis variation is performed by pulling away the saran wrap, crapping directly onto their face and then jumping up and yelling "What you talkin' 'bout, Willis?" alah Gary Coleman from Different Strokes.
At my high school reunion, my math teacher wanted me to give her a Hot Carl in the bathroom. So, I followed her into the john, assumed the position and delivered a Hot Willis instead.
5. The Tower Formerly Known as Sears
A moniker for the recently renamed Willis Tower in Chicago, formerly known as Sears Tower from 1973-2009.

Used by Chicagoans to avoid using the name Willis Tower.

Similar in structure to The Artist Formerly Known as Prince, which the music artist Prince crafted for legal reason to produce music outside the control of his corporate music label, until such time as he could regain his rightful name.
Passenger: Could you please take me to Willis Tower?
Cabbie: What you talkin bout, Willis?
Passenger: Oh, I'm sorry, I mean The Tower Formerly Known as Sears.
Cabbie: Sure.
6. STFUW
Short for "Shut the fuck up, Willis". Occasionally used as an alternate response to what you talkin bout willis?, however rather than not understanding the comment, the speaker would prefer the "Willis" to keep their god damn mouth shut.

Can be used against people whose actual name is Willis for greater effect, and additional points.
Willis: "Don't you think you'd better put the lid on that blender full of gunk before you plug it in?"
You: "STFUW!" *as you plug in the blender*

Willis: "I got another speeding ticket on the weekend, but didn't have to pay the fine because I'm awesome..."
You: "STFUW!"
