The best rapper ever existed.

His texts are very powerful. His favourite phrase is "STO CON MIO CUGGINO, NEGRO."
His best friend is Traffik Flexboy, the second best rapper in the word (better than Eminem and Lil Peep, oh ops, not lil peep rip).
His symbol is a fucking spider. He's drug addict because he loves XANAX and he smokes a lot of weed. When he plays his music in the disco he takes a pillow of MDMA so he can sing better.
Person 1: "Do you know Gallagher?"

Get the Gallagher mug.
A term used to indicate you got over on a situation, particularly when dealing with the government or other agencies/companies of authority. Derived from Shameless.
“Did you pay your ticket for when they caught you speeding?”
“Naw, I pulled a Gallagher and got it dismissed.”

“The return window was already closed but I Gallagherd the shut out of them and got my money back.”

Get the Gallagher mug.
To be a 6.5 million dollar third line checking winger, who doesn't contribute much at all and loves to whine.
I can't imagine having a Gallagher on my team. What a waste of money and time.
