(A). A jolly companion, a “brick.” (German, buhle, a lover; buhler, a gallant.)
We be three poor mariners Newly come from the seas, We spend our lives in jeopardy, While others live at ease; Shall we go dance the round, the round, Shall we go dance the round? And he that is a bully boy Come pledge me on this ground.
