Refers to when a man sits on a toilet and the tip of his penis dips into the toilet water. Usually affects gentlemen with large members or who use toilets with a high water level.

I think I got AIDS from tip dipping.

Dippin' the tip in 

When a man's penis is so large that he can only insert a small portion of it (the tip) into a woman's vagina during coitus.

Man this big dick is really a hindrance... every time I have sex I'm only dippin' the tip in.
