«The word jog appeared in the sixteenth century. Its etymology is uncertain: it may well be an adaptation of shog, a Germanic word with similar meaning which had been in English since the late fourteenth century, and which is a favourite expression of Nym in Henry V (2.1.42, 2.3.42). 'Shall we shog?' (= 'Let's go') has since become something of a catchphrase for bardaholics. Alternatively, it might have been a fresh onomatopoeic coinage, the sounds of the word reflecting the jerky movements involved.»
