Terrain Building 

Terrain building is an erotic gay act involving small, sharp shards, a funnel, and a man's gaping ass. The material is poured into the hole, then the procedure is repeated on the other partner. The materials used vary based on the couple, with aquarium gravel being the most common. Other common materials include glass, sand, and circuit board pieces.

Josh and Mark were terrain building again last weekend, they still both can't walk right.

terrain abuse 

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.
