how tf do yall be blacking out?

Like I just don’t get the concept of blacking out. People tell me it depends on your weight and your tolerance but as a young female with a relatively small-average figure and a low tolerance i have never blacked out.

i’ve gotten to the point where ive thrown up but then theres also the people who tell me that to black out you have to keep drinking AFTER you throw up. now that must be the most vile and disgusting thing ever. like after i throw up im done, im not having anymore for the next decade (or at least i tell myself)

so like what are yall drinking and how much to be blacking out, seriously how tf does it happen
