Är det en subkategori av incels?
Kanske även "mammas pojke" vuxna?
Är det ett brott att trängas?

In Japan, there are a certain type of people called 'Bumping men,' Butsukari otoko (ぶつかり男). They intentionally shoulder-check or shove especially women or weak foreigners in public spaces. When the victims speak up, these 'bumping men' claim women were walking slowly or she stopped in a weird place.
"...However, these 'bumping men' deliberately avoid male-female couples who are slowly strolling and male tourists who randomly stop while carrying the suitcase. Just targeting women before tackling them."
