phoncert 

When you call someone when you're at a concert, therefore transmitting the concert via phone. Phoncert.

Not to be confused with phig which is almost the same, but used at a gig.

I couldn't get time off work to see that band I like so my mate shared it with me via phoncert.

Poncert 

A concert in a place where it may be heard or seen from outside the perimeter fence, hence avoiding any cost of admission or payable fee.

Wireless Festival, Hyde Park in London. A temporary stage erected in the summer where the poncert is easily heard and/or seen from outside the paid entry zone.

Phonecert 

A "phonecert" is where you are calling another individual and they are singing and/or playing an instrument with a variation of songs giving that "concert" feel. However it is via call/video call therefore giving its name "phonecert"

Have you called Jack lately? His phonecert is amazing.
