Need more context about the author and the text. Is this from an NES? This is at first glance not an idiomatic usage of 'clear' and it's hard to figure out what could be meant, even by those who know the song.

'Clear' can mean 'get beyond' in the sense of 'one clears a level (in a video game)'; it could mean 'clean up, get rid of'; it could mean 'de-classify, make public' in the sense of 'clear for publication or broadcast', but none really fit in this setting.

Danke fürs Feedback, Buttermaker!

Lonelobo, the speaker is an American aging skate pro. Translating him and his friends is a nightmare, because their grammar is all over the place, they use a lot of colloquialisms and insider language and make up new idioms all the time ...

And no, it's nothing to do with Nintendo (that's what you meant by NES, right?)

NES = native English speaker

Worüber reden sie den davor und danach? Es geht doch in dem Gespräch bestimmt nicht nur um den Song, oder? Wie sieht die Szene aus, wo befinden sie sich?

Ich habe den Satz eher als Zustimmung zu den Sätzen gesehen, im Sinne von, "da müssen wir nichts streichen/zurücknehme", "das können wir voll unterschreiben", "Word".

Nicht dass das auch eine Anspielung auf das Skaten ist ...

gonick, by NES I meant Native English Speaker, which is an acronym that sometimes gets used on this forum.

I hold Cassandra's interpretation to be the most plausible.

The other possibility in the context of skateboarding is that to 'clear something' can mean to make it over or past an obstacle when performing a jump. But it doesn't really fit the gesture or respond to the song.

I am not really convinced by "clear" meaning "clear away" or "edit out"/"leave out", but don't have any convincing alternatives either. My one, totally far-fetched idea is - we cannot clear this life (in the sense of clearing an obstacle on our skateboards) and keep on going to new lives, so we need to fully engage in this one.

gonick - could you post a couple of the lines of the conversation before the ones in the OP?
