gillmania 

To get emotional and loud when drunk; night-outs may involve crying, shouting and throwing kebabs, and invariably end in pools of vomit

Emma: "What happened with her last night?"
Jon: "Oh it was so embarrassing, there was gillmania"

GillennialX 

It's when a Generation X population member behaves like ones of the Millennial generation.

David had a meltdown and felt entitled to help over a problem he was having, for a 40-year-old mature man he surely exhibited some GillennialX behavior.

Gillianna 

A funny outgoing girl, she always thinks less of herself even though others are jealous. She’s a very cute and pretty girl. You’d be lucky to know a gillianna, she’s shy at first but once you get to know her you won’t regret meeting her! She will always find a way to put a smile on your face. You’d be lucky to know a gillianna.

Gillianna is so pretty. It is so unfair!

gilliana 

A funny outgoing girl, she treats everyone respectfully and is never two-faced, one of the prettiest girls you will ever meet. Gilliana is normally very good with animals, especially large dogs, she always thinks less of herself even though others are jealous. You would be lucky to know a Gilliana.

Omg have you seen how pretty Gilliana is isn't not fair.

Gelfmania 

A fascist country, the country is a Laserpeeker sail boat. The country has King, the King sometimes has a queen who sits in the north of the country. There is also a Führer, who has superior decision making politically, but has no decision in the direction the country will sail. Gelfmania had declared war on the United States of America and began throwing rocks at the eastern coast of the USA.

“Gelfmania would have won the war against America is it weren’t for those damn seals!”
