A nap, taken by accident or deliberately, that lasts 1.5hours or more (usually longer than intended). When waking from a heinous nap, one generally feels groggy, unrefreshed and worse than they did before taking said heinous nap. A heinous nap usually will usually ruin a sleep schedule for several days.

Get the Heinous Napmug. This is a particular ball bowled in the game of cricket that is simply unplayable. When bowled this ball will travel at such high velocities the wicket sets on fire due to the heat created from friction. Typically the nip back off the seam is so severe an inside edge onto the stumps is guaranteed. Only a few players can produce such a delivery and thus the term is rarely used. However you will know if you have received a heinous razzler.
