TL;DR
Pipe dope is the trade name for pipe joint compound, a paste brushed onto male threads to lubricate assembly and fill the spiral leak path in threaded metal connections. Unlike PTFE tape it stays slightly pliable, so a joint can be backed off a fraction of a turn for alignment without starting a leak.
