MEANSUCKER WANNA GIVE YOU SKILLS ON THE TORTURE HELLCITYBUS.

Lust - You're really... enthusiastic. So much so that you tend to rush into things and not care if you do them well or not. (passive)
Gluttony - You really, really like food. You like it so much that you find it hard to concentrate on anything else. (passive)
Greed - You want money, 'cause you're in need. Getting more money is no trifling matter to you, indeed. You care about pretty much nothing but money. (passive)
Sloth - Baby Ruth! Baby Ruth! Nah, you're too lazy to go get a Baby Ruth. You're too lazy to do pretty much anything. (passive)
Wrath - You're just... so... angry. You hate everything. You just want to recklessly and violently smash things. (passive)
Envy - Whenever you see anybody else with anything, you want it. You don't care what it is, you don't care what it costs, you just want it. (passive)
Pride - You feel pretty full of yourself -- you're always strutting around and bragging about your accomplishments. Gotta watch your figure, though. (passive)

Learn Message

You have learned a new skill: skill.

The first skill costs 400 Meat to learn, but each subsequent skill costs twice as much Meat as the previous one.
None of the above skills can be made permanent.
Three pairs of these skills seem to be in opposition to each other, much like Knob Goblin nasal spray and Knob Goblin eyedrops. These skill pairs are Pride/Gluttony, Sloth/Lust, and Greed/Envy.
Each skill has one benefit and one drawback, many of which are currently unknown:

Each of the seven skills corresponds to the Seven deadly sins and give appropriate effects.
"Meansucker" was the name of one of Wesley Willis' demons.
