Acronym for "hot creamy load". It sounds similiar to ACL, so when you tell someone that you "blew your HCL", they'll assume that you've suffered some sort of injury before finding out that you're fine and that it's just a joke.
Person 1: Oh man, I was in the bathroom and I blew my HCL.

Person 2: Oh my god, are you alright??

Person 1: Yeah, I'm fine. I plan to do it again tomorrow as well.

Person 2: HUH??
