Can I prevent myself from viewing a friend's timeline or prevent seeing his name in my FB newsfeed?

[iMore Question]

Can I prevent seeing my friend's name in my newsfeed even just liking our mutual friend's post
When I scroll down in my newsfeed I could see my friend's name liking the post.

Or can I prevent my self from viewing my friends' profile?

Although I don't use FB, I'd like to think there's a block feature or the ability to un-friend someone.
