LONG RESPONSE, DIRECT ANSWER AT THE BOTTOM. Thinking through = to think about something carefully. To have a good reason, to think about the consequences and about all the convenient stuff before doing something. If someone said "You didn't think this through" it means they didn't think about it carefully, or about the consequences and their reasoning isn't good. For example, A girl stole a baby's ice cream. The father of the girl says, "Why did you do that? You didn't think this through." It means the girl didn't think about how she could get into trouble, and what was her reason to steal the ice cream and was it a good reason. So to answer your question, the person who said that has made the process of thinking something through into a noun. "The thing through", it is now a now, like "the dog" "the ball" etc. Minimal = a minimum amount, quantity, degree, it's negligible. - Negligible - small, not worth considering, insignificant, unimportant. "The thinking through (<--- noun) is (<-- verb) minimal (<--- adjective)." He's saying that "The process of thinking carefully about the situation is very small." ANSWER : It means "You don't have to think about it very much." Sorry it took so long to answer your question.

"to think through" means to consider or to plan something, it's very similar to "to think over". In this case, Ross is turning it into a noun (not usually done) in order to point out that laundry doesn't require much planning :) The joke is because Chandler is asking whether Ross has considered the results/implications of what going on a date with Rachel might mean for them, but Ross instead uses the question in reference to the laundry (and not his 'date' with Rachel).

Hi, THinking through means to consider something carefully especially before making an important decision
