I just read and contributed to a thread on YouTube rubbish and it started me thinking about words and phrases which by being mangled and/or abused in everyday language or speech. (NOTE: This thread is not about incorrect spelling although personally this does irritate me too). I set out two examples below.
Tactical - appears on ever increasing numbers of outdoor kit to be used by non-soldiers
Organic - seen this used instead of vegetable
Any other gems?
