How to use wsp
Learner’s notesIn plain EnglishText shorthand for "what's up?".
Lower case and unpunctuated. Like "what's up" in speech, it is a greeting more than a question; answering "nothing much, wbu" is standard. Not related to WSP as a company abbreviation.
If someone opens with wsp they usually want something or are starting a conversation — a one-word reply tends to end it.
