Most commonly used to refer to someone performing the acts typically associated with a basic bitch.

Like so many labels (e.g., hippy, hipster, chotch) basic bitch is a negative remark about a person's consumption choices. Whereas a hipster my be viewed negatively for the amount of time spent on novel clothing, music, or food choices, a bb is viewed negatively for the commonness of those choices. Think Uggs, Starbucks, Taylor Swift, etc. Another apparent criticism is a perceived increased interest of using social media, which when paired with a more "original" reader/viewer feels grating. All this makes you wonder if there is some happy middle ground where your music is accessible but not top 40, your food choices incorporate a blend of traditional and nontraditional offerings, and your clothing is novel but not too novel. I'm sure someone will come up with a catchy label for that in due time.

Girls at colleges and universities who dress in the most stereotypical manner of college attire.

a social climber bitch who is flirting with someone already taken/married and yet still flirting with someone else too while her so called bf/husband is not around.

Typically a white girl, who wears leggings frequently and enjoys Starbucks a little too much. Known for their love of Uggs and Lattes, basic bitches are taking over society.

A dude (usually a white dude) who does the same boring ass shit (patriarchal, status quo shit) as all the other dudes.

Example 1 : White dude who drinks beer is telling the not-dude brewer at a brewery how to make a better lager because he drank one once in Germany. Basic. Fucking. Bitch.
Example 2: Dude asks a woman's father for permission to marry (own) her with no indication from his partner that she thinks that's cute. Basic. Fucking. Bitch.
Example 3: A polo and khakis because that's what you and all your frat friends wore in college. Basic. Fucking. Bitch.

You're boring us, you basic, unoriginal, patriarchal nobody.

A white girl with thin almost to none existent lips who always tends to go to Starbucks, take a picture and post it on social media. Basic bitches also follow the newest trends and want to say nigga so damn and their always trying to be in everyone's business. Oh and they also like to represent themselves as "slim thick" even though they're just sticks.
