According to Merriam-Webster, risible means:
- Deserving to be laughed at; very silly or unreasonable
Christoper Hitchens wrote:
I can never quite decide whether the anti- Columbus movement is merely risible or faintly sinister….It is sinister, though, because it is an ignorant celebration of stasis and backwardness, with an unpleasant tinge of self-hatred.
I might use the word risible in a sentence like this:
His risible and painfully awkward attempt at picking up a woman at the bar ended in abject failure.
