The Herrero Vortex is named for the situation, whereby one finds themselves in the company of someone who talks continually, non-stop, about stuff no one wants to hear, and apparently has the stamina to go for hours. It's coupled with the circumstance, where you cannot easily get away. At first there may be an interesting point made, or you just want to be polite. After a while, it becomes annoying and you just want it to end. It could even affect your mental state, as eventually, your only goal is to escape. It gets its name from the Spanish word for blacksmith - someone who tirelessly and with fortitude, hammers away at something for hours at a time.
Dude, I got caught in the Herrero Vortex last night, at that poker game. This guy just would not stop talking, and I made some bad calls.
To Brush one's teeth while in the shower. Can also refer to shaving a guy's face in the shower. The word comes from Chris Herren on the ESPN special when he talked about how he shaved and brushed his teeth in the shower because he was too ashamed to look at himself in the mirror
