The people who are most likely to be dangerous won't be told how to do it safely.
They "KNOW" that the right way to do it is for the men to hoist the women off their feet and fling them around, and never mind if you let go.

Another safe basket hold is the Irish "Little Christmas". Everyone put R hand flat on neighbours waist. With L hand grasp the wrist of your opposite. Right foot into the middle and go as fast as you like. All safely interlocked.
