Facebook - not sure what this junk is but.....

Tweet

What setting do I need to find and activate to stop getting "friends" activity about the games they play and things that they "do" on their own FB page? Not sure what this is called but I log on nad particularly this one friend...my wall is littered with 2 dozen or more things she's done. Things like "cathy has just found a pig" or "cathy talked to a medium" or numerous things that "cathy" did and I have to literally "go to the next page" before I get anything else! Is there a setting I can choose to stop receiving all this game junk and stuff? I have looked at all settings and such, and can't find anything to click to stop receiving this junk.
