The heady crazed state achieved by a group of giggling people while indulging in a frenzied round of bonking each other's noggins with empty 2-liter plastic soda-bottles. The loopy euphoric mood can be heightened even more by (1) using the jumbo-size 3-liter bottles instead of the 2-liter size, since the bigger firmer bottle produces a more solid *thunk* and bounces higher with each klonk, and/or (2) using two bottles at once --- one held in each hand --- to simultaneously pummel the heads of your two nearest neighbors in the crowd.
My buddies and I went totally bonkers at the beach party last evening; it had been a really hot day, so we had accumulated such a sizable pile of empty soda-water bottles that there were more than enough for all of us to each swing two bottles apiece.
