When your child stays up all night working on a massive lego project and in the morning he/she has symptoms similar to that of an alcohol induced hangover: Sleepy, irritated, irrational, nauseous, thirsty and hungry. Adults may experience mild to extreme symptoms when building or helping children build a Lego project that requires hours upon hours of building. This can be prevented by reading the Lego box carefully. If the Lego has a reccommended age of 16+ you are very likely to experience a Lego hangover upon completion of said project.
"What's wrong with you Henry? Why do you look like you've been hit by a bus overnight?"
"I stayed up late last night finishing up my 3000+ piece Lego Effiel Tower."
"Sounds like a classic Lego Hangover to me. get some sleep today and make sure to hydrate yourself."

Get the Lego Hangovermug. 
My friend just bought a bunch of components and put it all together into a PC build, man those things are really like adult lego.
My friend just slapped a upper and lower tougher and put a red dot and 45 degree iron sights on it, building guns is like adult lego.

Get the Adult Legomug. The best game ever created, nothing can top the astounding power and tranquility of Lego fortnite, anyone who doesn't like it is retarded, it contains enemies that one shot you, it has hunger and temperature mechanics which kill you very fast, it also contains screaming autistic fucktards named Jay that won't shut the fuck up about how "bad" it is, I think it's the user. You can also build shit that doesn't work and fight giant lizard people that wombo-combo the fuck outta you and two shot you. If you aren't anything like Jay then you'll have fun.

Get the Lego Foot Massagemug. A word used by idiots talking about Lego bricks thinking there is an "S" on the end of a word that there isn't and never has been or will be.
Idiot "I was playing with Legos"
Normal person "You mean Lego"
Idiot "That's what I said, Legos"
Normal person "there is no "s" on the end, idiot!"
