1.
when on a long hike, and the summit (or awesome view) is near and within reach, one will go into "rampage mode"... a mode of rampage where one will use up all of his/her energy in a last ditch effort to reach the summit as soon as possible and at a mad pace.
oh my, he has gone into rampage mode again... i hope he will have energy to make it off the mountain before dark.
