You still haven't said what 'Deecher' is supposed to be if its not mocking Indian English?

Are you trying for the old joke of a spelling mistake? Teachers used to have a little fun writing their title as 'teecher' as 'ea, ee' are beginners mistakes.

But spelling this as a 'D' wouldn't apply to any native speakers as any common spelling error.

Do you know who this could mock? YOU!

Its really quite funny because it makes fun of your misunderstanding. It mocks how you think a 'D' and a 'T' might soundalike. (to non-natives with lesser listening skills that might be true).

Every time you write 'Deecher' its a fail but even worse you write LOL and even talk as if you have any place to judge or decide. Which makes you look like more of a dumbfuck.

Anyways, your explanations fail.
