Instead of wasting your precious life away with the laborious task of spewing out "no pun intended" the words "unintended" and "pun" have been fused together to create the ultimate word, saving an entire syllable: punintended
Usually in brackets: (pun intended)
no pun intended npi
lulz ensue when people mistake the word for 'pun-intended'
guy 2. excellent intentional pun
guy 1. in was unintended. i'm saving syllables
