At first a handful
‘CCP’ - 
‘illegal alien’ or some variation of it -
‘Death to Arabs’ (edit: it’s not a shibboleth but Israelis can really go fuck themselves) -
‘suicidal empathy’ (popularized by the likes of Gad Saad) -
'purity tests - oh yeah? here’s a pell grant tests a la Kamala
will add more if I feel like it
I might be wrong but i think it’s in part to stay in line with the naming conventions of communist parties elsewhere while also emphasizing national unity through “Communist Party of China” whereas “Chinese communist party” makes it sound like it’s a more ethnically oriented movement (lending itself to western propaganda about chinese immigrants by implying legitimacy over the Chinese, not China). Calling it the CCP helps let westerners get away with criticizing the entirety of China while claiming they’re only criticizing the government. Also they’re probably aware that Americans are morons and CCP is close enough to CCCP that they’ll react with cold war
Personally, I can’t wait for the about-face in 5-10 years when US xenophobia/propaganda rhetoric softens on China and dipshits start saying things like, “well that was under the CCP. The CPC are the good guys!” as if they are separate entities.
