When you or someone else gets so stuck in the mud/dirt/clay you dont think its ever going to come back out. Quite often you need multiple pieces of equipment or something 5x it's size to pull you out
I got my fourwheeler loser stuck the other day, had to bring down a 4x4 tractor to get it out of the mud. 2 atv's with winches couldnt even get it out ; it was loser stuck
