When you take your condom off after use and consume the contents, like it's a frube.
Apparently Will banged some girl last night, then after he was done, he took his condom off, looked the girl in the eye seductively, and started frubing!
freving is the next level of overthinking, it's used when "overthinking" is not strongenough to define you
A:hey bro, you had a good night ?
B:nah i couldn't stop thinking about ranodm stuff.
A:oh yeah, overthinking.
B:it's not overthinking anymore it's freving.
