to develop a taste for...; to be encouraged by initial success
A useful example one might hear in a potato chip ad is:
一度味をしめたらやめられない。 ichido aji wo shimetara yamerarenai.
If you try it once, you won't be able to stop.
The "aji" means "taste" and "shimeru" probably means, "experience" here. Having tasted something really good, a person comes back to it expecting the same tastiness.
一度ついたうそがばれなかったので、味をしめた彼はうそばかりついている。
ichido tsuita uso ga barenakatta node, aji wo shimeta kare wa uso bakari tsuiteiru.
He told one lie and got away with it. Having developed a taste for it, he lies all the time now.
