One level further than thirsty.
A guy who is thirsty for any period of time longer than 3months and up to 2years.
Extremely desperate to the point where even if his female subject rejects him multiple times he still perseveres in pursuing her. Despite the fact that she is clearly and obviously not interested, he never stops. Beware!!!!
"Girl this guy will not take a hint and get lost!"
"How long has this been going on??"
"Girl.. two years!!!!"
"He ain't thirsty..he dehydrated!!"
