A little help, please...

I was wondering if anyone in this guild knows what the word "rashiku" means? I can hazard a guess that judging from the times I've heard of it and just the internet, I think it means "like" (as in comparision) or "to act like" But this is my first year actually studying Japanese, so I'm not very positive...
Thank you in advance! Or anyways.

My penpal says it means like and when I asked him "as a comparison? "to act like..." or "like this/that" ??" he said "to act like"

so you're correct I would assume

All right, awesome! I've been having a hard time with that one...
So, thank you again!
