Is my phrase of the day. I heard it on the radio this morning in the context of thinking deeply and carefully. But thats not what I think it means. The best examples I can think of are:-
“Alan had mastered the art of low frequency thinking early in his life – he was thick”.
“John took the opportunity during double maths to do a spot of low frequency thinking – he fell asleep”.
Should be added to the list of words frowned upon by the LGA
