ice blocking 

The sport of using large blocks of ice to reach relatively high speeds down a grassy hill. The only required materials are Blocks of Ice, Towels, and a Grassy Hill. Simply sit on the block of ice (with a towel over it) and slide down the hill allowing minimal friction by using smooth ice and short grass. Let Gravity do its thing.

Often times it is called "Reverse Sledding" because of its popularity in areas that do not recieve snow. Ice Blocking has a huge following among California Teens.

Ice Blocking can be used as a great first date, or hours of endless fun with old friends.

Unfortunatley many parks have banned the sport and labeled it as Vandalism for its ruining of the lawns. However late night runs in the sprinklers have proven to be most fun and least obvious to law enforcement.

I had numerous bruises, but great memories after a night of ice blocking

Sock-blocking 

The act of preventing another fantasy baseball team from moving up in the standings by consistently outplaying them. Makes more sense if your team name directly refers to socks, such as the Red Sox or the White Sox.

Fantasy Owner #1: Dude, I've been trying to take 1st place for weeks now, but the Seattle Tube Sox keep sock-blocking me.
Fantasy Owner #2: I know what you mean, man. I haven't been able to overtake the Buffalo Business Sox all season.

jerk blocking

when you really want to jerk off, but someone like your sister, parents, or friends keep bothering you and won't leave you alone. It is very annoying and depressing.

I was trying to jerk off last night, but my sister kept telling me all these stories and she wouldn't leave me alone.

Wow, she was jerk blocking you all night.
