I heard in a British show this line:
We cleared this place out before, but it's just rammed up again. (source)
The subtitles on Netflix also give "rammed up", but this phrase doesn't make sense to me stand-alone or in this context. "Ram" suggests a forceful collision or banging. "It (the place) has rammed up" sounds nonsensical. For a moment I thought it might be "ramped up", but it doesn't seem likely.
I've put up a link to the series on YouTube. What does "ram up" mean here?
