I "hang on" so many times in a day :)
As if u dont know...hahaha
BTW I answered it thinking you are talking about the phrase commonly used over calls or chat- hang on....
And I guess you referred it to computers hanging on :)
When stoned I do come across that feeling quite often.
do you mean the past tense of "hang" (hung) ?
I have been really well hung since birth! (Sorry really bad joke!)
