def

Def is when you're too lazy or your IQ is too low and you don't know how to properly write the word "Definitely".

So instead of looking uncultured and write shit like "Defenitely" or "Definetly" etc. you Def that shit and save yourself from embracements.

I'm def a retard
I'm def gonna beat my meat after writing this definition.
