calling shortstack pushes with crap

[timmay28]

I make this call with no read on villian - new table. The odds are over 2-1 and the amount won't hurt me much if I lose.

Next orbit around he pushes again.

... it is 12376 for me to call a 23476 pot, nearly 2-1 again, but this time it hurts my stack a bit more.

I get fairly lost in these scenarios.
