A gusher is a place in the ground — usually an oil well — where oil or water shoots out with such force that you do not need a pump. The old picture is a black fountain bursting up over the fields. Water can gush this way too, but oil is the picture most people have. It is a slightly old, newspaper kind of word for that oil sense. When the burst is wild and dangerous, people at the well today more often talk about a blowout — though actually a gusher can also be a well that simply flows on its own, without that disaster colour. Much more rarely, someone who pours out talk or feeling is called a gusher; that looser use is less common than the adjective gushing.
