Knicker Bollock Glory 

1) Non-penetrative sex using knickers.

When the lady hasn't taken her knickers off and sex is still attempted through the knickers. It's a confusing mix of knickers, bollocks and goodness knows what else.

Some people try this as a contraceptive method.

"dude, we didn't have any condoms so we tried knicker bollock glory instead.

knickerjog

Going for a jog in just your knickers

Nancy: It's really muggy today, I think I might go for a knickerjog!
Gerrard: Really, what about your boobs? Won't they bounce up and down like kangaroos on space hoppers?
Nancy: No that's fine, I actually quite like it, and it stops me getting nipple rub!
