Usually a slang word to describe an online user who jumps from guy/girl to guy/girl dependant on how much they can give the said "baroka" or do for them. Usually more commonly found to hang around MMORPGs where it is easy to target gullible guys/girls with lots of online money.
"I can't believe that baroka just used me for those items and dumped me for another guy, just because he/she has gear she/he can use."
"So she stole his gear and went with another guy? What a downright baroka."
