He's kicking me!
Literal
He [topic-は] me [object-を] kicking [polite-ます]!
~ている marks an action in progress. The sentence is short and complete: subject, object, verb. Note that this could be an exclamation made in real time (a child complaining to a parent) or just a description — Japanese marks exclamation through punctuation and intonation rather than syntax.
