ballots were muchly splintered, as nothing received more than two votes (notwithstanding etaoin’s wasted own-vote) and only Alex irping correctly. The word seems to have been used only by Ben Jonson, twice: once as an adjective and once as a substantive.

here is the actual entry from the OED:

irpe, n.
Obs. rare.
[Origin unknown; found with the following in Ben Jonson.]
Some kind of gesture: ? a toss or jerk of the head, the act of perking.
Gifford suggested ‘a fantastic grimace, or contortion of the body’.
1599 B. JONSON Cynthia's Rev. V. iii. Palinode, “From Spanish shrugs,
French faces, smirks, irpes, and all affected humours, Good Mercury defend us.”

So irpe ? a., ? perk, smart. Obs.
1599 B. JONSON Cynthia's Rev. III. v,
"Maintaine your station, brisk, and irpe, shew the supple motion of your pliant body."
