Defoning

Apparently how Tom Delonge (Lead singer of Angels and Airwaves) spells deafening... <<Not that anyone should ever, under any circumstances, question his reasons...>>

"And the houses, laid out like targets, with a defoning sound, we watched them all go down." - The War - We Don't Need to Whisper - Angels and Airwaves

deffies

definitely, totally, absolutely, with certainty (adv.)

We should deffies go to the movies later.

Note: In most situations, deffies can be substituted for totes or probs to add an extra sprinkle of awesome sauce to your sentences.

Also note that deffies is not a derogatory term for a group of multiple people with extremely poor hearing.
