Years ago, during a visit to a Disney movie, my youngest son (10 at the time) accidentally referred to popcorn as cockporn.
I haven’t been able to order a bucket of popcorn in the cinema since, as I once copied his error. Now I am afraid to mention cockpo… popcorn in any public situation.
Worse yet, I had a marketing colleague who continuously mixed up YouTube with an infamous porn channel of a very similar name. To bypass this embarrassment, he started posting all marketing videos on Vimeo.
