My Many Nicknames!

The humans like to call me lots of different things, and sometimes you can actually figure out why! Here's an example:

• Jasper turned into a fake-Spanish diminutive becomes Jaspito (with a long "e" sound)!
• Shortening that gives you Pete!
• Adding a title produces Master P, which will be my moniker if I ever start rapping!

Of course, some of the nicknames just make no sense at all. "Tinito Mio?" Is that supposed to be Italian? Humans are weird!
