n.

c.1300, “small seagoing vessel with sails,” from Old French barge, Old Provençal barca, from Medieval Latin barga, perhaps from Celtic, or perhaps from Latin *barica, from Greek baris “Egyptian boat,” from Coptic bari “small boat.” Meaning “flat-bottomed freight boat” dates from late 15c.
v.

“to journey by barge,” 1590s, from barge (n.). The form barge into and the sense “crash heavily into,” in reference to the rough handling of barges, dates from 1830s, American English. Related: Barged; barging.
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. [ Late 1800s ]
