The horror and shame of getting old; especially when approaching the age of gray hair and arthritis.

The calmest person you'll ever meet. They can be shy at first but once you get to know them they're really out going. They know how to make you feel better with their jokes and hilarious personality. Sometimes though they pretend not to care deep down they're hurting. Never hurt an Eto
Every one needs Eto in their life

Anywhere east of I-35 in Austin, TX, in the five and a half (512 area code). In other words, east Austin, which, of course, is markedly less civilized and affluent than the western half. A good place to get jacked up - as well as str8 up got. Don't drive into this area in a phat ride with heavily tinted glass and gold rims, or some cholo might take a guage to your driver's side window - even at a stop-light.
"Biiiiiiiitch, we're ballin' thru E-to in this bitch-ass Impala we jacked, and nobody gives a shit! Whatuuuuuuuup?!?!"

Eto:

Sounds like an Asian name rhyming with "neato". Intellectual yet fun, unfiltered, strong, adaptable, and a penchant for the erotic. Also possessing the ability to make light in almost any situation.
Man that guy went full Eto at the funeral making everyone laugh.
