What do you mean by that?
WDUMBT? Could you give an example of what you are referring to?
|WDYM||What do you mean?|
|DYM||Did you mean|
|IKWYM||I know what you mean|
|IKWUM||I know what you mean|
|IYKWIM||If you know what I mean|
|IDK||I don't know|
|4MTK||For me to know|
|I can't even||I don't know what to say|
You can use WDUMBT to ask "What do you mean by that?" Most often, people use this acronym to ask others to clarify a previous statement.
For example, if your husband asks how he looks, and you send back "I'm not sure about those shorts," he may respond with "WDUMBT?" (Likely, you should have just responded with "ULKGR8.")
