Extreme exhibitions of silliness, stupdity, child-like behaviour, tomfoolery, shenanigans, capers, joking-around,
monkey business, larking about, toungue-in-cheek leg-pulling and/or high-jinks - taken to the absolute extremes of good taste and
socially acceptable behaviour but with good humour, a degree of
intelligence and no ultimate malicious intent.
Derived from the word Twunt but not as rude or potentially offensive in its use as the root word itself.
