Are they weird or its a crush?

I'm 18 and
This group of girls probably 16 are kinda weird (they are like 4) specially the blonde one always seems to give me attention and stares anytime I'm around, no emotion just stare, the next one stares at me less but used to chat with me out of nowhere at school, I even caught her recording me on her IPhone but said nothing, the next one is known as a 'hoodrat' and bangs older guys I used to talk to her to face I'm friend with her brother. The last one seems normal. So Yday Night at the bus stop they were All staring at us (friend and me). My Question can all these girls be weird? Are they my groupies or what lmao?
Tbh it don't bother me, except that no emotion stare

They sound weored and lost or you are very cute and they are weird.
Just ignore them

Whip out your wiener, and say "well?". Never know, you might get a four girl bj, epic fantasy ***

They probably think you're hot

Weird

There's some girls at my school who do this, and it really bothers me. Depending on what kind of relation ship you have with them(I don't really know so far)
-they're just looking at your looks (maybe they think your pretty)
-or they're doing it as a joke, just to weird you out. This is what the girls did, and it worked, because I would look away really quickly and I can hear them laugh.
