^I kinda do the same (on both counts, oddly enough)
When I eat ice cream from a cup/bowl I turn the spoon upside down before putting it in my mouth.
I stand awkwardly.
I have a serious foot-tapping problem (gets worse when I'm listening to music with double bass in my head)
When I do something with one side (like tap a finger or click my tongue or something) I have to do it with the other. It's not OCD, but it isn't too far. Fortunately, this has never been a problem for me.
