To Leap, To Hop
intransitive verb, ichidan verb
Not to be confused with 跳ぶ, this word has the same meaning. The reading is different, however.
The reading for this one is は because you're laughing (HAHAHA!!) at the person who put Nair (ねる) on their legs, then only finding it to be really painful, so they have to jump around to get the pain to go away.
That jumping bunny is SO cute.
