Following from the general definition on Wikipedia:

"Sino generally refers to China, the ancient-to-modern history of China, the culture of China, or the Chinese people."

Abbreviation for Chinese-esque, sometimes used abstractly to refer to Chinese people. Referring to someone this way is likely derogatory ( following a similar tone to chink or gook) but with direct connotation towards Chinese people rather than Asians as a whole. Used in some social groups as a racial slur towards Chinese people.
Person A: "I heard those sinos be kicking us out of our apartments because they we're perpetuating the virus"
Person B: "Yeah, well the sinos have always been racist to us nigga"
Person A: " Sinos literally put us in washing machines in commercials because they think we're dirty apes"
Person B: "Yea, well you can see where this all started"

Get the SINO mug.
A subreddit that is filled with propaganda and disinformation in support of the Chinese Communist Party. Anyone who goes against what the party says is downvoted and often banned, simply for expressing their opinion. Even people who post something that is completely neutral can get banned simply for participating in a subreddit that the people on r/Sino don't like. It is essentially the opposite of r/China, which is mostly against the party. People on r/Sino are known for praising communism, hating the West and countries that are friendly to it, denying atrocities committed by the Chinese government, the CCP that controls it, and the People's Liberation Army, the armed wing of the CCP.
I just got banned from r/Sino for saying that I support India's territorial claims.
