A Carmel the perfect girl bstfrn is an amazing rare unique friend. It is extremely hard to come by a girl best friend as great and perfect as Carmel. She is the bestest girl best friend there ever was and is a supportive and comforting best friend you can tell anything to. She is interesting considerate intuitive and very talented. She normally has a funny girl best friend and a boy best friend who can be annoying and stupid and do stupid things without thinking. She has little to no imperfections and has many people trying to copy and be like her. She takes the number one spot out of all of your friends let alone female friends.
Carmel the perfect girl bst frn is my girl bst frn. She is not insecure and is funny fun and entertaining.

She prefers to say bst frn instead of best friend for some reason

British Sexual Tension
Also known as "St John's Wood"
BST happens when you see a woman's elbow on the tube and you wanna shag her but she gets off at Maida Vale and you can't stop getting off at St John's Wood.

BST is short for “Booty Shake Tug.”

BST is a contactless, COVID-19 friendly form of sexual expression. When practiced correctly, a participant will bend over with their back facing their partner(s), spread their cheeks to display their booty hole, thus providing viewers with contactless contact from which to tug. BST became popularized during the pandemic in San Francisco’s North Beach amongst kinky yuppies, and sugar babies.
Last night was great. We had chipotle for dinner, then came home for 3 minutes of BST before watching Love Is Blind!”
