My pet hates are 'Parenting', and an new one which I keep hearing spouted ad nauseam by 'IT Professionals' (whatever they are!) - 'Leverage', as in "We need to leverage this up" - surely it should be "We need to lever this up" or "We need to apply leverage to this"?

It's also their practice to pronounce it the US way here in the UK, with a short 'e' instead of the long-'e' UK pronunciation, 'Leever'.
Prats the lot of 'em.
