Piterate 

When someone knows enough about the number π that they are unlikely to be taken advantage of by mathematical charlatans or cranks.

A premium tuition center is inviting Prof. Pilate to conduct a recreational math lesson on “The Joy (and Pain) of Pi” for its privileged students, so that they’d not only be numerate but also piterate.

Pierate 

1. A pirate who steals, pillages, and acts generally badass for the purpose of obtaining pie.

2. A pirate who IS a pie.

3. The ever rising costs of pie.

4. One (most often a pierate) who has eaten an entire pier, mistaking it for a pie.

5. A ratio, approximately 1.15, equal to that of pi and e.

No specific examples, though the more badass a person is, the more likely it is that they are, in fact, a pierate.

Examples of people badass enough to be pierates, though they aren't: Aron Ralston, John Hirsch, Sigurdur Petursson (may be a pierate, unconfirmed), Edward Teach, Grigori Rasputin

Pierate 

A feeling brought on when you've been looking forward to having a piece of pie all day long, only to find your roommate ate the last piece.

John was pierate with Shaun after he discovered Shaun consumed the last piece of cherry pie.
