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!
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.
