Gallagher’s Watermelon 

When two males and two females participate in a four-way and the female with the larger breasts lays down flat on her back. While one male performs missionary intercourse with her, the other female performs oral on the other male. When both males are prepared to climax, they closely surround the female laying down and discharge semen between her breasts. Next, the second female stands over the female laying down and proceeds to defecate on top of the pile of semen. When finished, she also surrounds the other female and they all watch as the female laying down begins to stir the angry mixture with her breasts. Then with an open hand, she violently slaps the mixture with commanding force, spraying fecal-cum on all participants much like the 80’s comedian Gallagher did to melons with his sledge hammer.

The bedroom required professional cleaning after an innocent couple’s dinner led to Gallagher’s Watermelon.

Gallagher show 

When a girl giving a blowjob chickens out and pulls her mouth away just before the guy climaxes, resulting in a chaotic but unavoidable shower of jizz. (If there are any spectators, they are strongly encouraged to wear trashbags and protective eyegear to avoid being sent home bitter and...well, bitter.)

- Yo, how was your date with Becky; I heard she gives a mean hummer...
- Nah, dude, it was a total Gallagher show.

Gallagher Sledge-O-Matic

1. The signature sketch of prop comic Gallagher, in which he smashes miscellaneous items with a large mallet not an actual sledgehammer. Apparently, a sledgehammer is too heterosexual. 2. A potent strain of methamphetamine, named after the above prop comic. Originating from around Hazleton, Pennsylvania. Taken orally, intravenously, anally, vaginally, nasally and smoked. The original lab was raided at the dawn of 2010, but is back in operation.

1. douche bag: I brought the clear plastic tarp for Gallagher's show. Hope he brings the Gallagher Sledge-O-Matic. Hee hee hee.

2. hazletard: I need a quarter hit of some Gallagher Sledge-O-Matic, bad. So I can suck truck driver cock for enough cash for a full hit, no homo.

Gallager's Angry Dragon 

When a man preforms the angry dragon but instead of punching the girl, he smashes her with a huge hammer. Used mainly at the time of break-up, because the girl does not usually survive.

"Holy shit! Ronald gave Sally the Angry Dragon last night....Gallagher Style!"
"Oh my god! is she okay!?"
"Hell no! he smashed her face like a watermelon!"

Samuel Gallagher 

The closest living relative of Harambe himself. Typical day for a Samuel Gallagher consists of 1) Either riding the bike, or due to inclement weather, dreams of said iron horse. 2) Memes 3) Beta god damn alanine. The most admirable of current specious roaming planet earth. Consider your self one lucky motor scooter to be graced with his presence.

Teacher: So little Tommy; What do you want to be when you grow up?
Young stone cold killer: Obviously I want to be Samuel Gallagher, you dumb bitch.

Silas Gallagher 

Silas Gallagher; a handsome, masculine individual possessing the most desirable of traits. Even though he may be timid at first, his romantic charm will shine through, and put him above the rest. Silas Gallagher's understanding and genuine compassion can put anyone at ease when they are around him. He is rarely judgmental, but rather always willing to listen with an open mind. He can out-drink any man against him, and if he wanted, could take your girl right out from under your arm. His smooth way with words will make any woman melt, and fall for him instantly. Though Silas Gallagher may have commitment issues; he is truly the epitome of a loving gentleman.

"Man, I wish I could drink like Silas Gallagher."
"See that man over there? That's a true Silas Gallagher."
