G-Delta - When a person with a 'Ga' last name takes a Greek letter and

When a person with a 'Ga' last name takes a Greek letter and makes a hyphenated mess out of it, probably to impress someone.

My G-Delta is 'Ga-Beta' and I use it to flirt with my crush.

I made my dog's G-Delta 'Ga-Epsilon' and now he barks at everyone.

My G-Delta is 'Ga-Nu' and my friends think it's a joke, but I take it seriously.
