Seismogasm

An orgasm that is so strong that the resulting undulations register on the Richtor Scale. A seismogasm can occur in either males or females. While a female seismogasm can often have high seismogasmic aftershocks, a male seismogasm usually results in a sticky gym sock, a cigarrette, and often sleep.

I gave her a 7.0 seismogasm wilth 4.0 aftershocks.

Seismographing

The act of lighting a match and sticking it in your dickhole.

My grandma caught me seismographing the other day! She was pissed!
