A terrible slang word for equestrian made up by Raghav because he is not very good at English and doesn't know how to pronounce normal english words that a first-grader should know.

It may also be used as a verb if one is so inclined: to equiester.

Also, if one is a super-nerdy medical student, like Raghav, or not very good at annunciating one's words, also like Raghav, it may often be confused with the word sequester (such as a Calcium pump) or esquire (such as a lawyer).
