Geillen is an asshole.

Geillen says " let's go to the party", then bails.

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.

Gaillen 

A peculiar being found in Turkish lore. This bizarre being was known to steal the right foot of loved ones.

The Gaillen has stolen my girlfriends right foot and took the foot back to her den so she can consume it.

Gillen Bag Pipe 

While doing doggy style you reach around with one hand and fiddle the vagina and with the other hand play with the breast.

Mom told Ally that last night Dad did me doggy style while fiddling with my vagina and playing with my boob. He called it the Gillen Bag Pipe.

Lewis Gillen

Thinks he’s the champ, would get knocked out by my right toe. His hairline is offside. His little brothers the bigger man. Secretly gay but hides it. Loves being aggressive after a few pints but scares no one

Just when we were leaving your man pulled a Lewis Gillen and tried to scrap everyone. Pure sausage

Guillen 

A type of smile that makes you want to punch someone and kill yourself afterwards.

His Guillen is pissing me off.
