Hello, I'm reading the usage of the idiom "get off" on thefreedictionary.<br/><br/>The first entry is "<b>get</b> sb. or sth. <b>off</b> sb. or sth.", whereas the example of this entry is "get him off <b>of</b> me".<br/><br/>So I'm confused; in this case is the word "of" required? or its existence is trivial and won't change the meaning?<br/><br/>Thank you in advance.
