A 5, 4 is a way of saying someone (typically a man) sleeps around based on a tx2 song called "I would hate me too" where he calls himself a 5"4 man whore
Person 1 "You know (insert name here)?:
Person 2 "yes."
Person 1 "(insert pronouns here) is such a 5, 4"
Person 2 "yes."

Get the reactor 4 mug.Lexington Av express train that goes from Crown Heights Utica Av in Brooklyn to Woodlawn in the Bronx. Has a total of 35 stops and when you wait for the train at Utica Av, it does not open its doors right away, you have to wait about 5 minutes for the doors to open while suffocating underground in the heat. The 5 train is a little bit faster than the 4 in my opinion.
"There is a Downtown express 4 train to Crown Heights Utica Av, approaching the station, please stand away from the platform edge."

Get the Type 4 Fun mug.FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).
"FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The designation FR-4 was created by NEMA in 1968.
FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.
Grade designations for glass epoxy laminates are: G-10, G-11, FR-4, FR-5 and FR-6. Of these, FR-4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics. Hence, FR-4 has sincewhen? replaced G-10 in most applications.

Fenhar FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable traitcitation needed will still use G-10 non flame resistant.

Get the 4 fingers up mug.In the Australian university system, 4 is a pass, and 7 is a full mark, so at the end of the semester, you will see a bunch of hustlers who did not watch a single lecture sitting outside during the exam block singing "4 is an open door," which is the urban version of the frozen song "Love is an open door, "where Anna met the evil prince Hans, the man she wanted to settle for life.
Hey man, how did your exam go?
It's been crazy.
Crazy？
Yeah, I winged every single thing.
All my life has been a series of doors in my face.
And then, suddenly, this one smashed right into my face
I was thinking the same thing, 'cause like
I've been studying my whole life to get into a university like this
And maybe I've been partying too hard, but I love the thrill of jumping on the edge of a 49 and a 50.
But with you (but with you...)
4 is an open door

Life could be so much more!
