In video games, an annoying-to-deal-with way to play against others in a combat-oriented/fighting game in which a player uses the terrain to their advantage, for example jumping on platforms to gain the high ground.

It isn't really "abuse", just the USE of terrain, but due to how annoying and unfair it is, people call it abuse.
Timmy: No fair! You terrain abused while using Ryu!!
James: DNC, you're the Chun-Li spamming Kikoken all game.
