If you are VFR and hit enough wake (or other) turbulence to suddenly put you 60 degrees nose up, you have probably overstressed the aircraft (especially something small like R22) and major structural failure is likely.
A sudden snap to 60 degrees nose up from cruise speed is about a 4 to 5g pull, perhaps more.
And, in a teetering head helo, your natural reaction will be to push forwards with the cyclic, probably inducing mast bumping as the g reduces and the probability of MR to tail boom contact.
If your chum actually wants to know how to do wingovers and pedal turns in a helicopter, that is a different conversation.
