Sore loser 

Someone who cannot accept losing and will bitch and moan while making every excuse while sporting out conspiracy theory even if all the evidence against them is overwhelming

Donald Trump: I only lost because they cheated!
Every sane person: Do you have any evidence to support your claim?
Trump: Just look
Everyone: We did and all of your claims have been proven false
Trump: Fake news!
Everyone: FFS. Such a sore loser!

A sore loser is someone who loses in a fair competition but whines about it on a constant basis, blaming everyone around them for their loss except themselves. Fun to taunt, but no fun to play with.

"Stop throwing chess pieces at me, ya damn sore loser!"
