Sloob has no real meaning. It could mean "God" or "Bitch" or "Cum" depending on how you phrase it.

Past tense: Sloopt
Present tense: Sloobing
Future tense: Finna sloob; shall sloob
(You cannot substitute "finna" or "shall" with "gonna," "going to," or "will." Otherwise you are not a true sloob and will go to Sloob).
