Untextable 

Unable to carry on a meaningful conversation via text messages. Doesn't promptly reply to text messages or doesn't text at all.

You can never get him to respond to a text, just call him. He's untextable.

untenable 

1 Something that someone tells you and they can't prove it.

2 Unable to substantiate with solid evidence.

3 unprovable

Example 1

Teacher: Give me your homework.

Student: Here's my homework; (pretends to hand it over) I wrote it on magic paper that only wizards can see and touch.

Teacher: That excuse is untenable. You still get a zero and detention.

Example 2

Person A: I'm telling you; Jesus really exists in the communion wafers of the Eucharist. Transubstantiation is irrefutable because sacred scripture and church doctrine supports it.

Person B: No, That's not irrefutable, that claim is untenable! The church has no palpable proof themselves, only St. Thomas Aquinas's word games. All that faith in your head has mushed the brain out of your ears.

Person A: Heathen! You know in your heart that God is real and that he loves you!

Person B: That's also untenable. But I'm not saying that I can prove you to be wrong.

Unreliable, untestable truth

The embodiment of faith.

Oh, you have faith do you?

The next time you feel compelled to use the word 'faith', why don't you try replacing it with: 'pretending to know something that I really don't know''.
If you really want to keep it simple you could just say: 'I have unreliable, untestable truth'.

Unbeatable Game 

Before bed, take two shots of NyQuil and chug a beer. After this, attempt to jerk off. No matter how it ends, you win.

"Last night, I played the unbeatable game. Best night of sleep I've gotten in quite a while."

Unbeatable Vow 

A vow taken by someone that they will not beat off (masturbate) until a goal that they have set for themselves has been achieved. It is a method of motivation, used mostly by athletes.

I'm taking an unbeatable vow until I beat Conner in a race.

I need an A this quarter, I'm taking an unbeatable vow until I do so!
