make something up

"Make something up" is a command given to someone when you want them to make an excuse so others won't be asking any more questions.

"He can't make something like that up!" is said when you know someone is speaking the truth because the information or reasons given given by this person are too complex or indepth to be dismissed as a lie; therefore, it is assumed to be true.

"You can't just make that up!" would mean that the person you are speaking to should not be foolish enough to think he or she can lie about (a specific) something and then expect to get away with it; it won't be credible. Or perhaps it would be credible, but it would be considered unfair. Whether or not it is credible would depend on the situation.
For example: Ed manipulates Sally into skipping one of her classes. Sally worries and tells Ed that her teacher will ask where he was during class. Ed responds by saying: "Make something up", meaning she should just lie to her teacher by saying she had something important to do (when really she didn't).

Second example: A six year old tells her mother that she saw her father kissing with a red haired woman in the car when she took a peak through her bedroom window. When her mother confronts her husband and he denies this, the girls mother could say: "Well, she can't make something like that up!", meaning the daughters information is so specific and also considering her age, it can hardly be dismissed as a lie.

Third example: A boss want to fire his secretary for not doing her job right. The secretary says that if he does so, she will tell the entire office that they slept together. Her boss could say: "You can't make that up", meaning it is unfair to him because it never happened.

Smoke something up

To develop a new solution to a problem, usually on an impromptu basis.

The expression "What have you been doing, smoking the crack pipe?" led to "You need to back away from the crack pipe" led to "Don't worry about it, we'll just smoke something up to solve that problem."
"What are we going to do about the brand new project requirement that we just received?"

"Don't worry about it, the rest of the team and I will just smoke something up tonight and have it ready for testing tomorrow."

something up your sleeve

Poker players who were (or are) less than honest, were known to keep an extra Ace or two stashed up their sleeve. This could be retrieved when needed either by means of slipping it out or by a spring loaded mechanical device that would slid the card out when pressed.
Everybody put your hands on the table. Slim, I think you've got something up your sleeve besides your arm.

Heres something I whipped up

In the game Smite, playing as the smith of the gods, it is the act of placing a turret into the field of battle announcing it to your enemies in a somewhat cocky optimistic tone only to have said whipped up turret destroyed within seconds making his hours of whipping up his creation from scratch in his shitty forge down the ass.
Example of a scenario
Announcer: Your left phoenix is under attack.
Player 1: (VDD) Defend!
You*Defending the phoenix from 3 enemies*: "Heres something I whipped up"
*They destroy the turret within 3 seconds*
*Enemies destroy left phoenix**Enemies gank you*
Player 1: (VVGG) Good Game!
Player 1: (VVGG) Good Game!
Player 1: (VER) You Rock!
Player 1: (VVGG) Good Game!

A phrase from the show "Lost" said by the ruthless mercenary Martin Keamy. It is most often used on the iMDB message board for "Lost" in response to a nonsensical thread or just to voice a certain type of annoyance against the OP.

The standard bu**s**t reply that a professed religious-freak half-heartedly tries to appease you with whenever you ask a "tough" theology-related question that he does not actually have a "ready" or "satisfactory" answer for, such as, "Well, if God truly loves Mankind, why does He allow bad things to happen to good people?", or, "Yeah, right --- well, tell me this, then --- if your 'perfect God' is so kind and compassionate and merciful, why did He allow my {some beloved relative/friend who became deceased way too early in life} to die?!"
I get sooooo sick ‘n’ tired of hearing that stupid-a** wooden-smile-expressioned response of "Well, that's something best left up to Jesus Christ," whenever I indignantly fire back a perfectly logical question at a local Bible-blabber who is trying to "bring me into the true fold” --- hey, I'm not interested in waiting for "Jesus Christ" to answer my question "all in His good time"!! I want an actual straight solid definite answer --- and one that truly makes logical sense to me --- RIGHT AWAY, not in FIFTY BLEEPIN' YEARS or however long I'm sposta hafta wait to "receive divine enlightenment”! How da HECK can a supposedly-enlightened "born-aginner" except me to wanna listen to his b**l-crap preachings or accept his beliefs if he himself can't even come up with a proper answer to a simple query that a non-believer would logically ask him? Zheee-yeeesh --- he isn’t even following the “old Scout motto” of “be prepared”!!
