I got caught out by the following instruction:
Twr: N.... into position and hold
Me: didnt have a clue, I heard the word 'hold' so i did just that
Into position and hold = Line up and weight in the UK.
Also the rate of speech from some US controllers can be quite daunting and they tend to give you loads of instructions in one sentence, mainly because they simply don't have the time to break them up into 2 or 3 different instructions like you tend to get here.
