Last Updated on September 30, 2026

Warframe slang falls into four groups: progression (MR, SP), modding (Forma, Potato, CO), fighting (EHP, CC, Nuke) and chat (LF, H, WTB). The ten below are the ones you will see most.

Tips that save runs
- The chat terms (WTB, WTS, PC) are on the chat commands page.
- Forma is both the item and the verb, and a "5 forma" build has been polarized five times.
- Blue potato and gold potato are the two colours; plain "potato" means either one.
Mistakes that waste runs
- Reading CC as Critical Chance in a squad post. In build talk it almost always means crowd control.
- Ignoring Disposition when you pick a Riven weapon. It scales the stats the Riven can roll.
