Starfleet (nickname)
Starfleet was a disparaging nickname given to Harry Kim by B'Elanna Torres in 2371. 

While in the care of the Ocampa, Torres queried as to what  was doing in the Badlands, to which Kim responded that Voyager was looking for them. When Torres corrected him, saying they were trying to capture, not merely locate them, Kim agreed, adding, "Consider yourself captured." Torres didn't find his comment funny, stating, "I don't find this at all amusing, Starfleet." ()
