unskippable ad 

A unskippable ad is a ad on websites like YouTube where it cannot be skipped. Every second on that ad is the more you want to kill yourself.

Jay: Yo, wanna watch some Kevin Hart On YouTube?

Brian: Hell yeah!

Jay: Shit, a unskippable ad.

Brian: FUCK!

30 second unskippable ad 

One of the single most annoying things about YouTube. They always come to ruin our video watching sessions, showing content we aren't interested in. With no skip button and being 30 seconds long, it is almost always essential to have AdBlock enabled so you never have to watch another ad again. Oh, and they also say 'Video will play after ad' where the skip button should be.

While I was watching some video vlogs on YouTube, I came across a 30 second unskippable ad on YouTube with no skip button at all. I kept refreshing the page, but all I got was ad after ad after ad.
