I was so sleep deprived I was starting to get punchy.
A term used by Nordic skiers (especially skate skiers) to describe groomed snow that does not support the weight of a skier, especially when the skier’s weight is all on one ski. The term refers to the undesirable event of a ski punching through the surface of the snow, probably causing the skier to fall. The snow on a ski trail is most likely to be punchy on the day following a moderate or heavy snow storm
If you describe something as punchy, you mean that it expresses its meaning in a forceful or effective way. A good way to sound confident is to use short punchy sentences. a punchy piece of writing or speech is short but very clear and effective
