Definition - What does Upboat mean?

Techopedia explains Upboat
The story behind upboat is that in the early days of Reddit, users noticed that because the B and G keyboard keys were near the V key, there was a tendency of users to jumble or substitute those letters. That led to upvote being rendered as “upbote” or “upgote.” Some caught onto this little glitch and started referring to upvoting as “upboating.” In this way, the slang term was born. It does not enjoy as much popular use now as it did in the early days of Reddit, but it has now become part of the Internet and computer slang lexicon.
