The "e" is replaced with an "a" because A stands for "asshole". A specific classification of a human-being who would generally attempt this kind of assault.
Example 1: IM GONNA RIP OUT YOUR FUCKING ASOPHOGUS BECAUSE IM AN ASSHOLE YOU BITCH
Example 2: I will make a quick incision just below your asophogus and in fact, it will hurt.

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
