|/use Warts-B-Gone Lip Balm|
To use: click on a lake frog to target it, check that the GCD on the lip balm is up, and press the macro. It will simultaneously apply the balm and blow a kiss at the frog. Target the next, check cooldown, and press again when ready.
Benefit: no more typing /kiss. I do not recommend adding a /target Lake Frog to the macro, as it will probably target one you've already kissed.
