If you like
the person whose dot you're referring to you might say: "I'd love to get my mitts on her dot," "I bet she has a tiny dot," "I'd like to erase her dot,"or "I would seriously
terrorize that dot."
If you were not fond of the owner of the dot (or the dot itself) you might say: "I'd like to kick her right in the dot."or "I'd like to erase her dot."
If it is your dot that is being acted upon you might say "Ouch! Right in the dot," "I have an itchy dot" or "my dot is
killing me!" (Try not to say this at a concert)
