A front wedgie, especially in the how you say.... Pussy.
Helen's thong style panties were so small it was forcing her to pull out Mervins all day, her poor cat must have been quite annoyed and/or chaffed.

A desperate, usually oafish, overly sappy individual who goes out of his way to win the effection of a female who is way out of his league, usually making himself look stupid at some point.
Ew. Like, that guy I work with is a total Mervin. He keeps asking me out, giving me flowers and writing dumb poems. There is no way a girl like me is going out with a fat moron like him.

When someone, or more frequently two persons, get on either side of you, grab your underwear (emphasis whitey tighteys) and lift up, essentially leaving you hanging in mid air via your underwear.

The trench is violated, if ya know what I mean.

A scale derived by the English mathematician and theoretical physicist Professor Ginger Ninja, which allows students using a sheet of A4 graph paper with 1mm squares, herein called 'mervins', to plot awkward, or complex points on a graph that shows the effect of temperature on the resistance of a thermistor. There are five mervins to a 'brick' and two 'bricks' to a 'box'.

Thus, any whole integer is always four mervins away from its next or prior integer; provided that each box on the y-axis is the equivalent to 5kΩ.

Simple, really.
MiniFunk: Using The Mervin Scale, how would I plot 54?
Proffessor: 54, would be four mervins below 55!
Jam and MiniFunk: Indeed!
