I wouldnt buy it. First I thought its lachs.com whats a fish and laughing would be lachen.com but lachst.com is terrible to speak and I presume a lot of people would not understand at the first point what its about.
If you had lachst.de it could be some kind of wordplay what could mean slang lachst de "are you laughing" but so...
I wouldnt set hope in it...
