As Soon As Possible.
This work has to be made asap.
Originally a military term dating back to WW1 when abreviations were being used everywhere.
ASAFP may also be used when the speaker is distressed, making it “as soon as fucking possible”.
“I need some fucking CAS runs in here ASAP, get some fucking cobras down here NOW and fuck up those goddamn T72s”. Via: urbandictionary
