I agree with the above responses that this is a movie reference, related to film shooting. If you want to really emphasize/exaggerate how many times you have tried something, you might say "take one hundred" or "take two hundred and fifty." However, to make things more complicated, in the USA, "take five" can also mean to take a break or rest (in other words, "to take five minutes off from working"). But this expression should use the number "five" rather than "two." Use: "Let's take five and go to Starbuck's." I'm not very young, so this expression might be for older generations. ;-)
