Skullduggery

We need to bring this word back into the daily vernacular:

skul·dug·ger·y

skəlˈdəɡ(ə)rē/
noun
noun: skullduggery
  • underhanded or unscrupulous behavior; trickery.

    Arbitrary use in a sentence:
    The level of skullduggery this administration is willing to commit knows no limit.
