The Washington Post calls them neologisms. BBC Radio 4’s ‘I’m Sorry I Haven’t A Clue’ refers to them as the Uxbridge English Dictionary

LYMPH – to walk with a lisp.

ABDICATE – to give up all hope of ever having a flat stomach.

REINCARNATION – to be born again as a tin of condensed milk.

LOVELORN – to really, really like grass

I wanted to invent new ones and give them a visual twist, for which I have coined the term – NEOLOGIGRAM – a visual intepretation of a neologism
