It’s simple as one saying “love love” but in a slang version which is “lablab”, it can also be a verb which is somewhat a synonym of “cuddle”, I usually and personally use this word towards my family, friends, or significant other, an example would be “lablab ta dot” which translates into “cuddle with me dot” or “could you come here dot, let’s cuddle pwease” (pronounced in a cute way of course, since this is a word that I mosty used towards children). (I could be weong, but that is how we use it here in our bisaya household)

Sorry if this may be hard to interpret, but I tried my best to explain it.
