Like

1. A word used as a filler for when you don't know what to say. Commonly followed by um or uh

2. A word commonly used by teenyboppers

1. It's like, um, when you, uh, don't, like, know what to say?

2. I hate myself a little more whenever I use 'like' as a filler because it makes me sound like such a teenybopper.
