Istnt 

A word or reference often used in place of the term "Isn't"

The word was first invented by the best looking, most amazing, girlfriend in the world who is also famously known for her incredible soccer skills, being half of the 'best looking couple to exist', and now for inventing the word "Istnt".

There istnt any girlfriend out there that is even close to being as good as Adri.

i swear to no one. it’s like saying istg but you’re not using anyone’s name. it’s more respectful.

Jennifer: everyone be quiet
riley: istg
sophia: don’t you mean ISTNO
