Extreme alteration of "Lets Get It". Popularized by a Soundcloud artist named "Lil Pump".(other aliases include "Professor Pump", "Liliam Pumpernickle", "Lyrical Genius", ect) Lil Pump was first seen using this term when recording himself inside of a car with Smokepurpp. Smokepurpp exclaimed "Look at all these shopping bags!", and then there was an uproar inside of the vehicle of them chaotically screaming "Essketit" without a determinable purpose.
"Essketit" can mean a plethora of things. It can be used to express excitement, pleasure, acceptance, ect. Basically, it means "I/We will prosper, let us proceed".
