==========================================================

【て+しまいます】

(1) It expresses completion of an action, emphasizing that the action in continuation has completed.

(2) It expresses feeling of regret, or the feeling that "I am in trouble/regretting".

This is the more casual version, which instead uses a verb’s stem form:

ちゃう／ちゃいます = to do by accident / to finish (casual)

ちゃった／ちゃいました = did by accident / finished (casual)

If the verb’s dictionary form ends with ぶ (bu) , む (mu) , ぬ (nu) or ぐ (gu), it becomes じゃう (jau) or じゃった (jatta).

じゃう・じゃいます = to do by accident / to finish (casual)

じゃった ・じゃいました= did by accident / finished (casual)
