Srs srsly means "serious." You're most likely to receive this abbreviation in text or chat messages, asking whether you are serious or stating someone else's seriousness.
Whenever you would use serious in an informal conversation, you can use srs instead. However, if you're incredibly serious, you may want to upgrade from srs to IDS.
