👉 The term 'preposition(al)' refers to a specialized form of preposition which is used as a modifier before nouns and adjectives. It's like when you have a special place called 'home' but don't know what the word means, it's like 'hoo-ha'.
Example sentence: "He doesn't care about prepositions."
The slang expression would be more subtle, like saying something that sounds funny or edgy. Like someone being sarcastic and making up phrases from everyday language to describe things in a playful way.
