Mostar 

A city of southern Bosnia and Herzegovina. The chief Turkish administrative and commercial center of Herzegovina from the 16th century, it passed to Austria in 1878 and to Yugoslavia after World War II. In 1993 ethnic Croats proclaimed the city the capital of the breakaway Croat republic Herzeg-Bosna, and many structures, including a historic 16th-century bridge, were destroyed as a result of fighting between Muslims, Croats, and Serbs. Population: 110,377.

Missoula Mortar and Pestle 

A marriage of the pittsburgh steamshovel and a skullfuck. Taking a shit in the empty eyesocket of a one-eyed hooker, then squishing your cock into it. Extra points awarded for the famed "Eye to Mouth" move afterwards.

Stump: I got rolled by a one-eyed hooker last night

Nick: How?

Stump: I just finished giving her the Missoula Mortar and Pestle, then she slapped me with a crowbar and took my wallet

MaSTAR Media 

The act of rotoscoping (tracing) in animation without giving credit.

The popularity of a particular YouTuber (MaSTAR Media) caused those to shame animators using the same technique as him.

Generally, you simply cut this down to MaSTAR.

"This is such a MaSTAR Media"

"Whatta MaSTAR!"

To "sit on a mortar" is to suffer the consequences of a 'dirty bomb' detonation.

"Unfortunately Your Highness, my husband had some dodgy prawn chimichongas for lunch and has sat on a mortar, thus he will not be able to attend tea."
