c.1300, "small seagoing vessel with sails," from O.Fr. barge, O.Prov. barca, from M.L. barga, from L. *barica, from Gk. baris "Egyptian boat," from Coptic bari "small boat." Meaning "flat-bottomed freight boat" dates from late 15c. The verb form barge into dates from 1830s, Amer.Eng.
Enter rudely or abruptly, intrude. For example, Her mother never knocks but just barges in. The term is also put as
barge into or barge in on to mean interrupt, as in Who asked you to barge into our conversation? These phrases use to barge in the sense of “bump into” or “knock against,” which may allude to the propensity of these clumsy vessels to collide with other craft.
