Dah

[Donald Trump]

from russian yes, used with the well-known retard entonation, means yes, what else? meaning the answer is so obvious that any retard would know… and all the retards speak russian, it implies…
So, its really a kind of insult to the russians coming back from… daaah! what else? the Cold War days, when they were the Evil Ones.
(At least thats what I… grasped, if you will, the first time Ive heard it… but not being english my mother-tongue, Im probrably wrong)

[Couch Potatoe]

Romanian/Russian word meaning yes.

Situation 1: A word used to veer off of a subject or a response to a question or statement that you dont know how to respond to.
Situation 2: This word could be used to retaliate from a verbal attack in a friendly and joking way.
This was first used as an inside joke when one friends status was in German and the other friend commented Dah because he didnt understand the status as a joke. Then, for every other comment he didnt know how to respond to he said Dah
