The first time we drove past the “don’t drive like a cock” sign, my mum looked at it was immediately SO confused - after all she’s a good semi-conservative Christian woman. My brother and I knew it right away but for the next half hour she guessed literally EVERY other word for cock (don’t drive like a rooster, chicken, hen, chick, bird, fowl, poultry) trying her goddamned hardest to make the sign make sense until my - at the time - eleven year old brother got fed up and yelled COCK at the top of his lungs from the back seat.
My mum was FURIOUS - we weren’t even allowed to say “heck” - until she realised he’d just been telling her what the sign was, and for the rest of the three hour trip our good semi-conservative Christian mother proceeded to amuse herself by muttering “cock” under her breath and giggling like a teenager every time she did.
