rba, re-buildable atomizer. Can refer to any re-buildable, whether dripper or tank.
rda, re-buildable dripper atomizer. This is a specific classification, but some tank systems can be drippers too.
rta, re-buildable tank atomizer. This has been a recent designation, to classify it as buildable and holds ml's of juice. While still being an rba, the t means tank.
rba/rda or rda tank. Some rba's can be used as tanks and/or drippers. personally am a big fan of dripping tanks.
Other abbreviations often specify specific rba's such as R91>Russian 91%, k.lite> kayfun lite, TGT> Taifun GT, flashi> Flash-e-Vapor V2, ... the list just keeps getting bigger every day. Often one has to search the thread when a new term comes out and go, oh, so the Russian 91 has gained R91 status. lmao.
You get use to it after hanging around to long, and then one automatically defaults to "Vape Speak" and find it hard to newbie speak. Usually will try and offer both terms when posting in the new member section, for my first post on a thread. After that its back to rba, rda, and toto too. lmao.
As always, welcome to the ecf, and congrats on your vape.
Vape long and Prosper.!!!!
Oh yeah,
P.S.: The cat bites!
