Yes, of course they did, but they could have put it in adult language too and not infantilise people.
I agree, however when you're dealing with a childish sense of humour it's possible to go too far the other way and be so proper and adult that it causes unintentional mirth.
When I joined the forces at 18, part of the NBC (chem / bio warfare) training covered "
defecation drills". (In plain English, going for a cr*p). We were told how to decontaminate parts of the suit, doff it, defecate, decontaminate, and don the trousers again. Some of the young men and women had not been subjected to doffing, donning and defecating before, but not to worry... Every leisure time visit to the loo from that point on was referred to as "going to carry out the defecation drill", and young men on nights out would occasionally have to "doff undercrackers due to defecation contamination" issues.
I have no doubt whatsoever that
@Drago still has the words "defecation drill" burned into his poor old brain.
