First Day Communist Kid - a person new to to communism, marxism, marxism-leninism or
marxism-leninism-maoism, who nevertheless thinks they know it all, even when facing actual
communists telling them they are wrong.
This doesn't refer to them having a
particular political position, just a lack of knowledge of even the sectarian positions they claim to have.
For example, a FDCK could lack knowledge of the Sino-Soviet split's importance or think that Scandinavia is market socialism.
