grammar - What is it called when someone says "like" or "alright"

I was talking with my friend and neither of us could think of the word for when someone says something similar to "And, like, we were totally, like, going to do this one thing."

To add to it, as requested, there are people that say things like "So, alright, this is what we're gonna' do, alright. First we need to (insert something here), alright."
