Not the scariest person as this was a group of 4 people but this was definitely an uncomfortable and unnerving experience for me either way.
2 weeks ago I was over at a friend's house. There were 5 of us there in total and me and one of my friends wanted to go to the store to get some drinks and possibly buy a video game. We drove up there at about midnight and browsed the electronics session. As we finished looking at the DVDs and walked out, a group of 4 teenage boys walked by us and one of them said "May I take your hat, sir?" in Patrick's voice from SpongeBob. We all looked at each other and after we were away from the electronics we shared some laughter at the SpongeBob reference, but I guess those guys heard us and didn't take too kindly to our laughter.
Later on as we were purchasing our drinks, those 4 boys were at the check-out aisle next to ours. I was glancing around the store as my friends bought their drinks and layed eyes on the boys, and they stared right back at me. I thought nothing of it. We walked out and entered my friend's car. My friends say they saw those 4 boys looking at us and getting in their car, but I personally didn't see that happen. As we drove out of the parking lot my friends started talking about the car that was driving behind us, which apparently was those boys' car.
Initially I didn't think much of it, they could have just been going to another store or heading home, but we drove around aimlessly for quite a while and it quickly became evident that they were following us. I'd never been in such a situation before, and it really scared me and made me uncomfortable. Even if, for some reason, we got out of our car and confronted them or they confronted us, I have no idea what they would have done, but it was a frightening experience nonetheless. Each and every turn we took, they were right there behind us. After what felt like forever my friend found a seemingly trafficless road and started going super fast. Perhaps not the brightest idea but we were all scared out of our minds. However, we had finally lost them and a wave of relief washed over us. As we headed home, we exchanged thoughts about Archer, Pixar movies, and how a simple SpongeBob quote managed to get us into a scary situation. At least it gave us all a story to tell.
TL;DR some guys said something at a store that made us laugh, they followed my friends and me out onto the road, we drove around for a long time and eventually ditched them
