Dude, I stayed up all night last night doing my lab report and now I can't see straight. It's like I'm drunk, but without any of the fun.

A condition in women that is analogous to the condition known in men as blue balls.
Such situation arises when a female is sufficiently aroused through foreplay with a man/women to the point at which her vagina becomes lubricated anticipating sexual penetration only for the man/women abruptly refusing to penetrate the aforementioned wet vagina.

Such an unexpected and non-erotic climax renders the lubrication of the vagina unnecessary and as a result it drys very rapidly forming a crust on the labia of the vagina.
1. Q: "Bro, did you put away that girl the other night? She was gagging for it"
A: "Na Bro, she wanted it but I said no and she got Crust Labs..... I still got a wristy though"
Q: "Niiiice"

2. Q: "Bro, did you bang that slut the other night?"
A: "Na Bro, I decided to Crust Lab her, that way she'll want it way more next time"
Q: "No doubt baby"

A school for kids more worried about their GPAs than getting more than 2 hours of sleep every night. Lab School students can be freakishly smart and overachieving, but they still have plenty of kids who got in in preschool and have turned into stoners. It shouldn't even be considered a real High School considering they don't even have a football team, and the rest of their sports teams are far from admirable. Technically Lab School is the University of Chicago Laboratory Schools, however only the pretentious new kids call it that.
Random Adult: What school do you go to sweetie?
Lab School student: I go to Lab
Random Adult: Oh wow!
Lab School student: Yeah, so basically a little less rich than a Latin kid, and smart

Someone who is addicted to being in lab, constantly running experiments, and can't stop to go home even though they know that it's healthy to maintain a personal life because they find themselves chained to their experiments through an obessive personality type.
I walked into lab at 2 in the morning to check on my bacteria and found that Suzie was still running a gel. What a lab rat (forget that I was there too...)

The computer lab employees at Elk Grove High School that hunt down students off task. These sad individuals find joy in locking and printing pictures of an off task students computer, then tattling on them to their teacher.
"Oh man my computer got locked" complains Mick. "Its those damn lab nazi's again!" Jeff explains.

To dry lab is to make up data in a scientific experiment, as opposed to observe or experiment in order to obtain it. Usually this is done in response to pressures to finish the experiment by unethical researchers.
It was getting past 4:30, so Kagame decided to dry lab her experiment in organic chemistry by plugging in plausible figures.
