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.

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.

Seismic Lethargy 

An extreme state of lethargy, cause unknown, but very tiring. Seismic Lethargy can strike down its victim without warning and usually whilst they are trying to do something. It usually affects young males and reported cases are more prevalent in the warmer summer months. The consensual course remedy is to remove the patient from the environment that is inducing the lethargy.

Rhys is unable to continue today because he is suffering from Seismic Lethargy.
