Waspish

Got bitten by a wasp in the park the other day - it was interesting in a kind of painful way. Turns out I am allergic to them, my foot swelled up to the size of a balloon and I got all itchy. Oddly I think the wasp sting has also given me some kind of personality change, ever since the sting I have been prone to little outbursts, temper tantrums and hissy fits. Is this what they mean when they say someone has a waspish personality?
