SLS

Social Logic Supporter; the logicall response to Social Justice Warriors, they can be taken as the good people under them, like feminists before the start of third wave feminism.
Those who can be identified as Social Logic Supporter will be aware of discrimination and racism, there where it actually happens, and other socially unacceptable things. However SLS's are Libertarian, so they will never try to obstruct free speech in their process of raising awareness of such things.
Girl : You know, Islam is actually a terrible religion that preaches for the restriction of female rights and advocates for the punishment of gays, we must make that clear to people!

Sjw : Woah, stop being a discriminating racist!

Boy : She isn't being a racist dude, she is being an SLS, you better listen to her

SLS

Abbreviation for Space Launch System. NASA's new moon rocket for the Artemis program, set to bring humanity back to the moon in the 2020's.

Currently the most capable rocket in the world, until SpaceX's Starship launches. SLS is designed to bring the Orion capsule onto a TLI (Trans-Lunar-Injection) course. It was proposed in 2011, as a replacement for the cancelled Constellation program, intended to launch in 2016. It did launch, but only 6 years and $10B overbudget, and is often criticised for this. Nevertheless, it is extremely cool and I can't wait to see it launching crew.
Person: OMG SLS is fucking cool! When is the next launch???

IB SL Math

A waste of time. You learn derivatives, but it is unnecessary unless you want to be an engineer. Don't take this course if you love your free time.
