It has just been noted that you are not a member of the inner party yet, and thus have not been cleared to use the word Jam.
The term "jam" can be used by musicians to insinuate "free playing" which, unless you have undergone a rigorous diversity training programme, could lead to accidentally riffing on capitalist keys, such as A flat minor, which as we all know is the relative minor of B major, which is a codeword used by right wing extremists to signal oppression of women. Please make sure you book yourself on a course as soon as possible.
Mmmm, jazz
Jazz is acceptable, as it's MOBO. Unless it's being played by a white male, in which case it's cultural appropriation, and therefore a hate crime.
You look white. Are you not guilty? Eh? You bloody should be.
