link man
n.— «The captains and deckhands don’t outrightly charge any specific amount for concealing anyone aboard their ships. The go-betweens, or as they are known in the street lingo there, “Link Men” demand from N300,000 to N150,000 before hooking an intended traveller to a ship.» —“Takwa Bay: The Stowaway gateway” by Jossy Idam Sun (Lagos, Nigeria) May 13, 2006.
