This is almost definitely caused by a setting in your system preferences:
Maybe you have the new trackpad (or a macbook) in which case this part of the system preferences might look a little different, i know trackpads/laptops with 3d touch probably have some variation in regards to the appearance of the trackpad preferences, but it must be a setting thats analogous to the setting near the top left in the above picture, 'look up & data detectors'.
To me this would suggest one of 3 things:
You're accidentally clicking the "shortcut" you assigned to 'look up' when you're intending to hit the shortcut assigned to 'click'
Your trackpad is defective/worn-out and thats why its doing this.
You have 'look up' and 'click' assigned to the same shortcut. (which doesn't seem to be possible on my computer)
You've been 'clicking' everything using 'look up' (not sure thats possible either).
An easy solution to this is to simply disable any "mouse shortcut" for 'look up'. You can still access look up by right clicking.
For anyone who just wants to see whats happening with their own eyes (I know I was pretty curious):
if anyone on a mac highlights all of
30 rockefeller plaza new york ny
(or any address) and right clicks it, then selects
Look Up "30 rockefeller plaza new..."
then they'll see the same pop up.
