Tacoma Narrows Bridge 

A fetish among STEM lecturers. Found in nearly every engineering related slideshow, this works as a perfect example for resonance, amplitude, wavelength, harmonic motion, unstable process, twisting motion, finite element analysis, CFD simulation, aerodynamics, calculus I, calculus II, calculus III, miscalculation, general relativity, or the meaning of life. A link leading to a video of the wobbling Tacoma Bridge can be added to any presentation to fill out empty space. Sophisticated students may even use it as an academic source in their Master's thesis.

-Did you find any good content for our group project?
-Yeah, there's this mad video of Tacoma Narrows Bridge!

Tacoma Narrows Bridge 

Similar to the sex position "The Eiffel Tower", the Tacoma Narrows Bridge is performed by having a girl on hands and knees, where sweet fellacio is happening at one end with one happy male, while the dirty plowing is occurring with man #2 in the back. However, a real Tacoma Narrows Bridge occurs when one man blows massive load early, and his body succumbs to the moment and he collapses, preferably into a river.

Hot dog! Dale and Troy hit me hard last night with a Tacoma Narrows Bridge. Troy lost control and yeeted himself into the river. We had to call the Coast Guard!

narrow urethra 

A curse upon mankind. Only known victim of this curse so far is Hank Hill.

Hank's narrow urethra made him take a minute longer to take a piss, and his chances of impregnating someone is extremely low.

straight but not narrow 

An open-minded heterosexual.

It's cool to wear pins on your bags that say "Straight but not narrow", unless you aren't straight, in which case it would be much more appropiate to sport a rainbow pin, unless you think rainbows are ugly, which they are, because all those colors don't mesh together very well.
