Steal, while visiting somewhere you would not normally go. Should not be an item of value or use to you, simply something that you take a liking to.
Where did you get the street sign?
Oh, we souvenired that in Glasgow.

A bastard, usually left by men who have been called to war and died. The wives would then later learn that they are pregnant; a souvenir by their dead husbands.
Mary was distraught to learn that her husband had been killed by an onslaught of Germans. She was even more distraught to learn that before going to war he had left her a souvenir of a bastard unborn baby.

Commonly used for corn, or any other food including nuts that will show up in your poop the next day.

Giving you fond memories of the meal you ate the previous day. And sometimes even surprising you, when you were not aware that was one of the ingredients in that stew, soup, or casserole your mom made for you.
I better watch it when I take that second helping of souvenir food. I know it will come back to visit me tomorrow.

Clothes, alcohol, or something kept on a nightstand that you steal from someone post-sex.
I have this great book of philosophy I stole from Vinny after we boned. Sex souvenir, #sorrynotsorryy.

Painted Souvenirs is one of the most unique activities through which photos are turned into hand made paintings.

A variety of artists are doing their best in turning their clients' favorite photos into 100% hand made paintings.
The effect is amazing...
