[aisygirl11]

LIAR! I tried that after this video and and all i got was mustard and ketchup in a bowl of water

[theninjamandude]

@aisygirl11 that is because you did not experience a small heart attack beforehand. that is a crucial step in the process.

[aisygirl11]

@theninjamandude i was kidding dip shit

[theninjamandude]

@aisygirl11 so was i, dip shit.

[aisygirl11]

@theninjamandude wow real mature just throw it right back at me thts what stupid people do u no

[theninjamandude]

@aisygirl11 really? I thought what stupid people did was misspell basic words and use them in a structurally retarded, half-assed insult, much like you're doing now. but i don't want to litter Benfer's comment section with a ridiculously long argument against a 3-year old, so i'm afraid that this is the last response you'll get from me. goodbye, you unintelligent asshole.

[aisygirl11]

@theninjamandude See im 14 years old haha thts the thing and umm i can spell stuff wrong if im not in school. Ok so if you want you can read this then get off and go tell your mommy im not spelling words right. Ok you go do once your done big whinny ass baby god damn ur like brother hes 15 he whines about EVERYTHING and u, ur whinning about me not spelling right and trying to come p with the greatest come backs well u no what GO TO HELL and u can tell the devil he spells stuff wrong mk :D BYE!!!
