on your left 

What cyclists say by convention as they pass each other on the road, or occasionally as they ride near pedestrians. It is infinitely more cool than mounting a dorky little horn or bell on your handlebars and squeezing it at every opportunity. It may not be always be strictly necessary, but it is a little courtesy that will get you cred and make you look experienced.

<College student races to class and overtakes a pack of spandex cyclists, but remains silent.>

"On your left! On your leeeeeft!" You gotta let us know! Where are your manners?"

<sound of metal crunching and muffled screams. this guy will not have to say this for a while.>

left on read, left your bed 

As we know, being left on read is when someone reads your text/email/etc and does not reply. Therefore, "left on read, left your bed" means if a potential sexual partner does this, you will never allow them access to your body for sexual purposes, because they lack manners, so they can lack your sexual energy as well.

Left on read, left your bed

He left me on read then hit me up 3 months later at 3AM with a "you up?". Denied! Left on read, left your bed! That's sucka shii.

Shouted at peds, slow cyclists, skaters while passing on the their left side. Preventative against left turns.

Used while riding at speed on a bike path or streets. OnyourLeft!
