Calvin Flex

A "Calvin Flex" is a braggadocious remark used when an individual has a lack of redeemable characteristics and has to rely on bragging about possessions and/or small achievements as a means to validate self-worth when receiving praise or the interest of others. Those who use such statements will often times be ignored or made fun of. This is due to the unwanted and awkward implementation of a"flex" used during a conversation. A "Calvin Flex" is often used when having a conversation with a woman who has a physical appearance rating between 2/10 - 10/10 (beggars can't be choosers).

Girl: Hey, let's go out to eat!
Boy: I don't like eating in my car 'cause I don't want to make a mess in my brand new 2019 Honda Civic EX.
Girl: Wow, nice "Calvin Flex"
Boy: I made bread.
