“I usually just fast forward through the commercials.”
You are having a conversation with your friend about a TV commercial, but you haven't seen it because you don't watch commercials. This is how you explain that you have a DVR and always skip commercials.
I usually just fast forward through the commercials.
You use this phrase when the action you're describing seems easy, simple, fast, unimportant, or unexciting:
I just googled "new york florist" and that was the first shop that came up, so I called them.
A: What did you do this weekend?
B: I just sat at home and watched T.V.
You "fast forward" a video or an audio recording in order to move to the next part more quickly. When you fast forward through a part of the video or song, you are skipping that part and not watching it.
"Commercials" are TV advertisements. In the U.S., several commercials are shown in a block between segments of a TV show. "The commercials" refers to this period of time when commercials are being shown.
