seismic shift

A major change. (Seismology is the study of earthquakes.) The implication is that the change being described is so significant that the earth will move under your feet. Like paradigm shift, this phrase has become overused marketing hype.

In just the last century, there has been a seismic shift in the treatment of women in this country.

Ego-seismic

Thinking about the cause of an earthquake relating to yourself.

Maybe us moving, redirected the epicentre of U.S earthquakes to where we were from. I like to think of it as Ego-Seismic thinking

seismic dump

A seismic dump is a poop that once leaves the bowel, instantly crashes into the bottom of the toilet, often creating tsunamis, vibration, panic attacks, chaos, and of course seismic activity that registers on the national level. Often accompanied by a wet arse, stains in the toilet bowl, and a horrendous smell that can linger for days like radiation fallout.

I was taken off my feet by the shockwave of tom's seismic dump. When he walked by, thats when the fallout smell hit me and put me in a coma.
