When you are so in love with someone that you feel like you are tripping on drugs in a way; you are *high* on love and they are all you think about. Sometimes people lose sleep over this because their thoughts about this person keep them up at night.
person #1: Hey what's wrong with Nate? He's been acting different lately..
person #2: Ah, he's love trippin' over his new girlfriend.
person #1: Is that why he's been all giddy and not been able to concentrate in class?
person #2: Yup.
Psychedelics and other drugs that 'trip' a person out may leave permanent indentations on their nervous system, LSD (acid) is best known for this. When a person trips so hard or so many times they become locked into a permanent trip, they are considered Triplocked. People may also become mildly Triplocked, which is why those who have done many psychedelics in their time can trip out on marijuanna as if they had taken LSD or other halluciogenics that have them mildly triplocked. Triplocking has been reported from all types of hallucinogens.
"Ever heard of that triplocked old man who wonders around center city thinking he's a glass of orange juice? Holy shit I wonder how hard he had to trip to end up that way."
"Ever since I tripped balls on Ecstacy everything seems brighter when I get high."
