A step beyond ordinarily wrecked — mega knackered is what happens when regular exhaustion gets stacked on top of more exhaustion, until you've reached a level of tiredness that feels almost theatrical. You're not just tired, you're spectacularly, cosmically, almost impressively destroyed. The word mega adds an element of dark comedy, implying the speaker has somehow lapped the normal fatigue dial and ended up somewhere absurd. Used with a mixture of complaint and reluctant pride that you've achieved peak depletion.

Three back-to-back night shifts and now a family dinner — I am mega knackered and running purely on spite.
