Don’t make the swedish in Spain

Fer retxes a s’aigo – make lines to the water! Used in Mallorca when you are not doing anything or doing something without any meaning at all.
Hacerse el sueco – to make the Swedish! When someone plays dumb – no offense intended though.
Ponerse las botas – put on the boots… When you do something with abandon, mostly used as ating until you really cannot eat any more.
