look up any word, like lemonparty:
 
1.
tuning more than one bitch at once
to get into multiple pairs of pants.

The act of tuning is to be really nice to a girl and tune her so she is ready for you to make a move and not reject you

To be on the multitune usually requires skill and many different technologies. it is most successful when the girls dont know each other
