Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.

A 50/50 mix of Powder Heroin and Powder Cocaine. Creates the feeling of being in a relaxing warm bathtub mixed with the desire to complete an insurmountable task. This volatile mix is usually mixed into a drink because snorting it is too risky.

Based off of the ice cream. You work so hard for that chewing gum at the bottom and, after all your hard work, it tastes like shit
Substitute this into life and relations and you get a fairly philosophical meaning to an 89p ice cream.

A pony loving faggot who sucks huge and massive dick. He is an asshole and his first name usually starts with an N. His friends all hate him, and they normally refer to him as a pony faggot, as well as spam him over the internet. He likes to eat chips with his mouth open because he is a fatass. He has no brothers or sisters because he was adopted by 2 gay Russian supermodels. His vagina smells like horse because he is only fucked by ponies. In fact, that is the only type of porn he likes.
Screwball: I LIKE TO START PUNCHING BABIES IN THE FUCKING FACE WHEN PEOPLE START THROWING PONIES ALL OVER THE FUCKING PLACE, BECAUSE I LOVE PONIES. BRONY FOR LIFE.

Normal Person: Shut up you ponyfucker, nobody likes you.

Screwball: I LIKE TO EAT CHIPS VERY LOUDLY OVER TEH MICROPHONE. THEY ARE YUMMY BUT NOT AS GOOD AS PONY DICK.
