Hive has several “tip tokens”, also known as “engagement tokens.” These tokens are usually on Hive Engine (or Tribaldex, same thing, different look). They usually have the purpose of rewarding Hive users with a token (or fraction of a token) and/or showing appreciation and encouraging engagement.
These tokens are usually issued by replying to a Hive user's post or comment with a command, typically the command starts with an “!”, such as “!BEER”. A bot in the background then sends a token to the person being replied to as a tip.
BEER is one of the earliest tip tokens. PIZZA, LUV, and LOLZ are often-used tokens on Hive.
