Boxerbating 

The ridiculous act of multiple fast paced simulated uppercuts and jabs without an actual opponent or partner.

Example:
Hugh Jackman, looked absurd boxerbating for the final 3 minute thrilling climax of Real Steel.

bikerbating

Riding your bike trainer while strangling your monkey until your chain and floor are both covered in white lightning.

I used to hate riding the trainer in the winter until I put the bike in front of the tv, got some porn, and started bikerbating.

Boxerbation 

The pathetic act of simulated boxing, through high speed, rapid succession uppercuts, jabs and haymakers, against imaginary opponents.

Boxerbation is usually done in private if the if the person still possesses a shred of dignity.

Public boxerbation although still legal in most states is generally frowned upon as to ridiculous to warrant acknowledgment as an actual human function.

In the film Real Steel, Hugh Jackman almost pulled off being human until, his bizarre display of public boxerbation in front of an audience of millions.

Boxterbating 

When two people get inside two separate boxes and masturbate in the same room together.

My sister and I live in a one room studio apartment. For privacy we practice boxterbating opposed to masturbating out in the open.
