To be in a state of "lert" is when your in the mood to basically fuck shit up.
When you are "lert" there is the constant feeling that nothing will satisfy you but a good
time, seeking and pleasuring hot women or partaking in copious amounts of questionable activity frowned upon by most cultures (yes like masturbating in airplanes or doing lots of hard
drugs).
Lert and fuck go hand in hand.
Jesus once said: Fuck

Fuck this history exam I'm feeling lert as fuck.
Boss #1: Man I could go some
pussy, alcohol, fast cars, drugs, fights, parties, boats, hoes and some

Boss #2: Me too. Lets get
fucking lert.
